Re: [R] Why does a 2 GB RData file exceed my 16GB memory limit when reading it in?

[Leandro Marino]

David,

If the ".Rdata" contains more than one object you could (and maybe should
use) the SOAR package (from Venables). This package helps you to split the
objects over multiple RData files. It's useful when you have numerous
medium-large objects in the workspace but doesn't use then at the same
time.

When use SOAR::Attach(), for instance, it loads the current name of all the
objects and retain than available in the searchpath but without load then
to the memory. As you call, they will be loaded into the memory.

If needed, you can update the object and then store it again with the
SOAR::Store()

For my use, this package is terrific! I use it with an analysis that I need
to repeat over medium-large similars datasets.

Re: [R] Microsoft R Server

[Leandro Marino]

John,

as I know Microsoft has owned the Revolution Analytics and is continuing
the development of the Revolurion R with a new name Microsoft R. Note that
Microsoft R has an open source stable version. I'm not quite sure which
modifications they are doing on it. I suppose that this modified version of
R is the one they are putting in their servers.

As I could search few weeks ago they inform us that all R packages works
with their version.

[R] Show all elements

[Leandro Marino]

Hi,

Look to the following code:

set.seed(1)
dados =
data.frame(valor=rnorm(100),var=sample(LETTERS[c(1,2,3,5)],100,replace=T),peso=rpois(100,2))
dados[1:10,]
dados$var - factor(dados$var,levels=LETTERS[1:5])
table(dados$var)
 A  B  C  D  E
31 31 19  0 19

When I try to use summarize, Hmisc package it shows me the result without D
category.

g1 - function(y) wtd.mean(y[,1],y[,2])
summarize(dados[,c(1,3)], llist(var=dados$var), g1,stat.name = 'med')
  var med
1   A  0.02589377
2   B  0.37123239
3   C -0.57820359
4   E  0.39584514

How do I get med = NA or something else with summarize?

I realy need to the function to return all factors in the var even it they
are an empty set.

thanks in advance.

[R] Suggestion in justify in write.fwf {gdata}

[Leandro Marino]

Hi,

Sometimes, I need to do some hard work when exporting files using gdata
package.

It will be very useful if the justify parameter of write.fwf can receive
vectors. In some jobs I need to left and right justify in different columns
of the same file.

Nowadays, I do a lot ow this working in preparing manually each file.

I was wondering something like


justify=c(rep('right',3),'left',rep('right',2),rep('left',10))

in a file that has 15 columns.


Best,
Leandro

Sorry, the i deleted the first part of the email.

Today I downloaded the Ubuntu 12.04.2 32bits to install it on the
virtualbox (in a windows machine). After it i have installed R with
success. Before I installed R I installed the LAMP as I show in the first

Re: [R] Windows RT or Windows 8

Dear Levke,

R works perfect with windows 8. I didn't update to the 3.0 version but I
guess that will work too. Windows Rt differ from Windows 8 in a lot of
things really don't know if it will work.

Re: [R] Editor to program with CRAN R

[Leandro Marino]

 I think that if you're not familiar with emacs or vim I suggest you to
use RStudio. If you're a programmer that knows how to use eclipse I think
eclipse with statet it will be the best solution. Another option that you
have is the notepad + + with NppToR plugin

 Best,

Re: [R] Order a data frame based on the order of another data frame

[Leandro Marino]

*Hi,*
*
*
*i think that you are making a mistake. When you use *
*
*
order(rownames(snp.matrix$fam)) you're sorting the data, so it will be in
the same order of the data_one.

If rownames() are defined correctly in data_one, you only have to do:

data_one[rownames(snp.matrix$fam),]

Note that it's good to check if all elements from rownames(snp.matrix$fam)
are in rownames(data_one).

setdiff( rownames(snp.matrix$fam),rownames(data_one))
setdiff(rownames(data_one),rownames(snp.matrix$fam))

2012/3/5 francesca casalino francy.casal...@gmail.com

 Hi, I am trying to match the order of the rownames of a dataframe with
 the rownames of another dataframe (I can't simply sort both sets
 because I would have to change the order of many other connected
 datasets if I did that): Also, the second dataset (snp.matrix$fam) is
 a snp matrix slot:

 so for example:

 data_one:
xy
z
 sample_1110001-0.3352623 -1.141462-0.4032494
 sample_1110005 0.1862424  0.015944 0.1329059
 sample_1110420 0.1309120   0.0040055960.06117253
 sample_2220017 0.1145205  -0.1250900540.04957881

 rownames(snp.matrix$fam)
  [1] sample_2220017 sample_1110420 sample_1110001
  [4] sample_1110005

 I would like my data_one to look like this:
   x   y
z
 sample_2220017 0.1145205  -0.1250900540.04957881
 sample_1110420 0.1309120   0.0040055960.06117253
 sample_1110001-0.3352623 -1.141462-0.4032494
 sample_1110005 0.1862424  0.015944 0.1329059


 I have tried these but it doesn't work:
 data_one[order(rownames(snp.matrix$fam)),]
 data_one[rownames(data_oen)[order(rownames(snp.matrix$fam))],]

 Thank you for your help!

Re: [R] Tinn-R

[Leandro Marino]

*Paul,

I didn't understood your problem with tinn-r.

I don't work at a lab, so i have no idea how it can be your specific
problem. I think it has a problem with R + Win 7 that is about the changes
in the permissions at Program Files folder. What am i doing to cheat this
problem.

1) Install R and Tinn-R at c:/MyProgs
2) Change the security permissions and give all full control to all users in
the machine and apply the new settings.
3) Open Tinn-R and configure the Rprofile.site file. **(R  Configure 
Permanent) If it necessary you can change some parameters or put some
packages to load by default and you can change the default Cran mirror.
4) Open R inside tinn-r and wait to install all packages

What version of tinn-r and R are you using? I'm using R version 2.13.1
(2011-07-08) in 32bits and 64bits at the same machine with Tinn-R 2.3.7.1

Yep, you have to configure TINN-R when you install a new release of R.
**
In the Option  Application  R you have an option to use i384 or x64. I
didn't understood the problem of the changes in the R path.

 You don't mention which version of windows or R.  Setting thus up for
 all users on a Windows 7 system has been more trouble for me after R
 re-organized their install so that  Rterm.exe is no longer in the
 path. It is in that subdirectory i386 or such.

 My notes say Even if you change the paths, TINN-R will not save what
 you do because it always looks at R again and tries to guess the path
 when TINN-R starts, and IT ALWAYS GUESSES Wrong. That's why, under the
 menu where you set those 2 paths (for rterm and rgui), you also TURN
 OFF the option to always use newest R. 

 And Tinn-R has to be reconfigured whenever R gets updated.

 But if y ou have tinn-r working, I don't mean to stop you.  The
 problem is that a seemingly endless stream of new users can't make it
 work.  Maybe you post your install recipe on the Tinn-R website, it
 would help people out.

 In my experience, TINN-R does not work so well, and most new users are
 recommended to try instead Notepad++ with the addon components
 R2notepad++ or Rstudio.  I have MS Windows setup tips here

 http://web.ku.edu/~quant/cgi-bin/mw1/index.php?title=Windows:AdminTips

 Until I see evidence otherwise, I'm concluding that TINN-R was the
 best in 2008, but it is harder to configure now and there's no reason
 to prefer it over Notepad++.  Real Men[tm] still use Emacs, but new
 users may not have enough muscles :)

 Hello,

 I have to run a set of crosstabulations to which I need to apply some
 weights. I am currently doing an unweighted version of such crosstabs using
 table(x,y).

 I am used with SPSS to create a weighting variable and to use WEIGHT BY VAR
 before running the CTABLES, is there a similar procedure in R?

well, if You wish, You can always write scripts in R and then send it to

directly to R running on remote Linux server.

[R] ggplot2 = bar size

[Leandro Marino]

Hi,

i am newbie into ggplot and i thow that i have to learn a lot about this 
package.

I am doing this function to draw an graphic:


library(ggplot2)
posx - theme_text(angle=45,hjust=1,face='bold',size=12)
posy - theme_text(angle=0,hjust=1,face='bold',size=12)
y1 - c(1,4,6,1,8,10,6,1,5,4)
x - qplot(x=factor(paste('nomes',1:10),labels=paste('nomes',1:10)),
   y= y1 ,
   geom='bar',margins=F,
stat=identity,xlab='',ylab='Y LABEL')
x + opts(axis.text.x=posx,axis.text.y=posy) + geom_bar(fill=c(rgb 
(000,100,000,maxColorValue=255),rep(rgb(110,139,061,maxColorValue=255),
9)))

Now, I want to know how can i change the size of the bar. I want to draw it 
thinner than it appears into the R Graphics Console.

Another doubt is how can I use another format into the y label, called in this 
graphic 'Y LABEL'

 Dear all,

 I have a file which I've converted from NetCDF (.nc) to text (.txt)

 console) of the file appear as follows:

 As you can see, there are a lot of NA values before the actual  
 numeric values start further down the dataset. My problem is that  
 I'm having trouble reading this file into R. I think the problem  
 lies with the sep= argument, although I may be wrong. I tried the  
 following command at first, as the data appear to be comma separated:

 read.table(test86.txt, skip=43, na.strings=-, header=FALSE,  
 sep=,) - test86  # skip =43 due to meta-data information being  
 held in the initial rows
 Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,  
 na.strings,  :
  line 29 did not have 25 elements

 I then tried sep= , followed by sep= but received a similar-type  
 error message (although line 29 doesn't appear to be especially  
 different from the rest).

 I subsequently tried using sep=\t and then sep=\n. These both result  
 in the data being read in without an error message being displayed,  
 although the data are formatted as follows:

 head(test86)
V1
 1 _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,  
 _, _, _,
 2 _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,  
 _, _, _,
 3 _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,  
 _, _, _,
 4 _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,  
 _, _, _,
 5 _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,  
 _, _, _,
 6 _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,  
 _, _, _,


 dim(test86)
 [1] 179899  1


 Instead of one column, I'd expect there to be 720.


 I think I'm getting something wrong relating to the sep= argument  
 (or possibly mis-using na.strings?). If anyone has any solutions to  
 this then I'd be very grateful to hear them.

 Many thanks for any advice,

 Steve


Two problems,

1. Your first line above has one more column/entry than the subsequent  
lines. If that is correct, you need to use the 'fill = TRUE' argument  
so that all subsequent rows are filled to have the same number of  
columns. If the above is due to a copy/paste error, then disregard this.

2. You are using a '-' (hyphen) as your 'na.strings' character, when  
the data is using a '_' (underscore).

Additionally, I would use 'strip.white = TRUE', to aid in getting rid  
of extraneous white space around your fields/separators. That will  
also help with column separations.


Thus (on OSX) with the above data copied to the clipboard:

  read.table(pipe(pbpaste), na.strings = _, sep = ,, fill =  
TRUE,

Many, many thanks for all the answers!

Notepad++ looks very promising although it does not have a project file
management facility. But it has a very clean appearance. I'll have to look
into SciTE which also sounds quite good. There seem to be some good
alternatives.

Meanwhile, I found a freeware application which helps to make Tinn-R truly
portable: JauntePE (http://www.portablefreeware.com/?id=1452) virtualizes
access to the registry and file system and can easily be used to make also
the ini settings portable. Thus, everything will be on the USB stick.

Thanks again,

Assunto: Re: [R] xlsReadWrite package repository for Ubuntu

You perhaps missed the key point in Uwe's response, which is that the package 
is only available under Windows, as it depends upon Windows specific 
functionality (MS Office API via a third party library which is available for 
Windows only) to natively read and write Excel files.
Thus, there is no package version available for Linux, or OSX for that matter.

If you need to read Excel files under Linux, you could look at the
read.xls() function in the 'gdata' CRAN package. This package requires that 
Perl be installed, as it calls a Perl routine (xls2csv) for converting the 
Excel file to a CSV file, which can then be read into R.

If you need to write Excel files under Linux, you can use a Perl routine that I 
had posted back in 2007:

  https://stat.ethz.ch/pipermail/r-help/2007-July/135968.html

and have updated since then to handle Unicode issues. I am attaching a 2k text 
file here with the updated routine.

HTH,

 If you consider the CRAN master to be liable, it tells you for

[R] LATTICE

[Leandro Marino]

Hi,
I am having some problems using bwplot(lattice) in my data. I want change
some parameters:
1) Fontfamily to serif
2) The size of the font
3) Put it in a bold face
4) Change de color of the lines

How can I do that?! Now, I am using this to plot my boxplot.
dados - data.frame(varsep=as.factor(rep(1:2,10)),i=runif(20))
bwplot(dados[,'varsep']~dados[,'i'],xlab=names(dados)[2],ylab=names(dados)[1
],panel =function(...){panel.grid(v = -1, h =
0);panel.bwplot(...)},font=2,fontfamily='serif') 

Thanks for any help on advance and sorry about my English.

[R] RES: memory limit

[Leandro Marino]

It depends of the number of the variables. If you are using 2 or 3 variables
you can do some things.

I should you read about ff package and ASOR packages they manage the dataset
to do some kind of IO.

I'm currently working with very large datasets that consist out of 1,000,000

rather consider C++/Java.

I am facing a problem in merging two datasets.
I have given codes to the names which are common in both the datasets and

When I gave gave the following command

merge(df1,df2)

only those rows and columns were merged which were  having common codes.
When I viewed the results, only common codes are seen and the remaining

Can anyone guide me in this regards?
How should I merge these two datasets completely without loss of any

The colors() function returns all of the names.

The ?col2rgb has examples that produce text tables like what you want,
but doing it graphically will be hard:  there are 150 different colours
to show.  There's some code in the ?rainbow examples that displays a
smaller number of colours.

 Does table(ceiling(runif(100,0,50))) give you something like you want?
That's a neat(-ish) solution of Moshe's multinomial formulation.

More generally, if p is a vector of probabilities you can simulate
independent indicators with cut(runif(N), c(0,cumsum(p)) and then
multinomials by tabulation.

However, it is inefficient for large N, and awkward if you want
replicates, which is why we have rmultinom(). In the present case use
rmultinom(1, 100, rep(1/50,50))

Assunto: [R] initialize a matrix



Dear R users,

I'm trying to write a function which returns minimum,maximum,mean of a
vector(power)

I've done the following :
VAR-function(power,length){
for(i in tml:length)){
tvar[i]-i
pmean[i]-mean(power[i:i+deltat])
pmin[i]-min(power[i:i+deltat])
pmax[i]-max(power[i:i+deltat])
varmax[i]-100*(pmax[i]-pmean[i])/pmean[i]
varmin[i]-100*(pmean[i]-pmin[i])/pmean[i]
Resulats-list(tvar,pmin,pmax,pmean,varmin,varmax)
}}

p.s. tml is a variable which is grater than 0 , deltat is a constant defined

The problem is that tvar is unknown for R.
So I have to initialize tvar,pmean...
Should I create a zero matrix with length of the vector? And how to do it?

Thanks for help

[R] RES: Error while plotting matrix

[Leandro Marino]

You aren't using a matrix.

This is a vector so you can only use:

tvar - rep(0,(length-tml0))
pmean - rep(0,(length-tml0))
pmin - rep(0,(length-tml0))
pmax - rep(0,(length-tml0))
varmax - rep(0,(length-tml0))
varmin - rep(0,(length-tml0))


Why are you not using an data frame? Do you have to output this in a list()?

Dear R user,

I have written a function which returns max,min and variation of a power
(see below)
Power is a given matrix(1,n)

I call the function
Variation-VAR(p,(n-deltat))

Now the problem is when I want plot(Results[1],Results[2]). Not possible!
I become the following error (in english it means: Error in
as.double.default(x) :Object cannot be transformed in double)

 plot(Variation[1],Variation[2])
Fehler in as.double.default(x) : (list) Objekt kann nicht nach 'double'

Any suggestion?

Hier is the function:
#Computing variation of the power
VAR-function(power,length){
tvar=pmean=pmin=pmax=varmax=varmin-matrix(data=0,ncol=(length-tml0))
for(i in tml0:length){
tvar[i]=i
pmean[i]=mean(power[i:(i+deltat)])
pmin[i]=min(power[i:(i+deltat)])
pmax[i]=max(power[i:(i+deltat)])
varmax[i]=100*(pmax[i]-pmean[i])/pmean[i]
varmin[i]=100*(pmean[i]-pmin[i])/pmean[i]
Results=list(tvar,pmean,pmin,pmax,varmax,varmin)

}}

You can do this plot saying to R that your file is a time series with the

   Thanks, Petr.
  
   After fiddling around some more with my code I found out that this
seems
  to
   have something to do
   with the number of records the table I'm reading (here: column
B112).
  Somehow,
   changing the
   number of records for B112 changes the numbers in the error message
-
  though I
   don't quite
   understand how the number of records influences the axis intervals
or
  their
   labels, since I define
   those explicitly...
 
  Neither I. So I sent it to r-help maybe somebody else will know. If
  you debug code of axis.Date you find that after some computing there
  is this comparison where range is based on your input data (in your
  case x), and z is from defined at sequence of dates.
 
  z - z[z = range[1]  z = range[2]]
 
  and this comparison results in character(0), when plotting with this
  artificial example.
 
  plot(1:100, seq(405,410,length=100), axes=FALSE, ylim=c(405,410),
  col=red, pch=15,
  type=o, ylab=metres above sea level, main=Main Plot Title)
  axis(2, at=405:410, tck=1, col=gray60)
  axis.Date(1, at=seq(as.Date(2004-01-01), as.Date(2008-06-01),
  by=month), labels=seq(as.Date(2004-01-01), as.Date(2008-06-01),
  by=month), tck=1, col=gray60)
 
  I presume, that your x is from different interval of dates or it is
  not a date.

 My data comes from a groundwater monitoring program. Once a month the
water surface is
 measured in some 170 stations, and I've been using R to visualize these
 measurements. In this
 particular case, the water table ranges between approximately 406 and
408
 metres above sea level,
 hence the y axis interval between 405 and 410.
 The values of my column x are dates of the format -MM-DD. If
something
 were wrong there,
 then I guess I would not be able to plot my data at all. But using the
limits
 of 2004-01-01 and
 2008-06-01, I can plot all the timelines for my 170 measuring stations
without
 any problem. But
 since it's now July, I wanted to shift the view by half a year. So I
used
 search and replace in my code
 to change to 2004-07-01 and 2008-12-01 (plus six months in both cases).
That's
 when I got the
 error. I almost have a feeling that R doesn't like the empty part of
the
 graph for July-December...  I
 don't understand why this happens, but maybe it has something to do with
the
 comparison of ranges
 you mentioned.

OK, It seems that you are right. Maybe you could add some expected x
date/time values so that x axis will have no NA values.

x-seq(as.Date(2004-01-01), as.Date(2008-06-01),by=month)
y - seq(405,410,length=54)
y[50:54] -NA
plot(x, y, axes=FALSE, ylim=c(405,410),col=red, pch=15,
type=o, ylab=metres above sea level, main=Main Plot Title)
axis(2, at=405:410, tck=1, col=gray60)
axis.Date(1, at=seq(as.Date(2004-01-01), as.Date(2008-06-01),
by=month), labels=seq(as.Date(2004-01-01), as.Date(2008-06-01),
by=month), tck=1, col=gray60)

as you see, then everything works. However I think that it is pretty close
to bug in axis.Date, maybe somebody can enlighten us both :-)

 Dear R help list

 I have recently started using R to visualize time series of
water
  level
 measurements. The code I wrote
 does exactly what I want:

 plot(x, a$B112, axes=FALSE, ylim=c(405,410), col=red, pch=15,
 type=o, ylab=metres above sea level, main=Main Plot Title)
 axis(2, at=405:410, tck=1, col=gray60)
 axis.Date(1, at=seq(as.Date(2004-01-01),
as.Date(2008-06-01),
 by=month), labels=seq(as.Date(2004-01-01),
  as.Date(2008-06-01),
 by=month), tck=1, col=gray60)

 Now I wanted to shift the data visualized by 6 months, so I
replaced
 
 2004-01-01 by 2004-07-01
 and 2008-06-01 by 2008-12-01. Instead of the desired plot, I
get
  an
error
 message stating
 (forgive the perhaps faulty translation into English, I'm
working on
  a
German
 version of R):

 mistake in axis(side, at = z, labels = labels, ...) :
   length of 'at' and 'labels' different, 50 != 54
   
Those two calls have different length
   
at=seq(as.Date(2004-01-01), as.Date(2008-06-01), by=month)
labels=seq(as.Date(2004-01-01), as.Date(2008-06-01),
by=month)

It is a lot of tables, in S-plus I was using

write.table(questgeral[[i]],

write.table(questimp[[i]],
Y:/questimp1104m.txt,dec=.,sep=;,append=T,quote=F)
}


How can I put the row.names before the col num in R? And how can I remove
the x in first line and the number 1 and the ^t in the second line before
Q05?

Thanks for the advance!

[R] exporting ftable

[Leandro Marino]

   How can I export an ftable object in the same format that appears in R
command window?
For testing that i was using this example that is in help of this function.


## Start with a contingency table.
ftable(Titanic, row.vars = 1:3)
ftable(Titanic, row.vars = 1:2, col.vars = Survived)
ftable(Titanic, row.vars = 2:1, col.vars = Survived)

## Start with a data frame.
x - ftable(mtcars[c(cyl, vs, am, gear)])
x
ftable(x, row.vars = c(2, 4))

## Start with expressions, use table()'s dnn to change labels
ftable(mtcars$cyl, mtcars$vs, mtcars$am, mtcars$gear, row.vars = c(2, 4),
   dnn = c(Cylinders, V/S, Transmission, Gears))


When I tried to export the object x i have thsis result:
V1 V2 V3
1 0 0 0
2 0 0 1
3 1 2 0
4 0 6 1
5 0 0 0
6 0 2 1
7 2 2 0
8 0 0 0
9 12 0 0
10 0 0 2
11 0 0 0
12 0 0 0

I used to export:  write.table(x,c:/x.txt)

Thanks in advance!

[R] RES: how to automatically maximize the graph window (under XP) ?

[Leandro Marino]

Hi,

you can use the jpeg(), pdf(), bmp() functions. In this function you can
determinate the size of the graph, background color, quality of the image.

Assunto: [R] how to automatically maximize the graph window (under XP) ?



Hello,

I'm trying to produce graphs automatically from data stored in database.
Before saving the graphs, I would like to maximize the size of the graphs.

The best would be to directly open maximized windows with x11() but up to
now I failed doing it.
I tried different widths and heighs but I never managed to obtain a full
screen window.

Is there a command to do it ?
Thanks in advance,
Ptit Bleu.

PS : I'm under XP

[R] RES: Invalid object error in boxplot

[Leandro Marino]

HI Miriam,

the problem is that you have the Date and some other factors in your
database.

try to use the

lapply(your_base,class)

and see what appears. If you have any kind of factor or date you cannot use
boxplot.

If you verify that only V1, V2 and V3 are numeric you can do the box plot
with this sintax:

boxplot(your_base[,c(V1,V2,V3])
or
boxplot(your_base[,c(5:7)]

Hi,

I'm trying to make a boxplot with the data at the end of the message, and
when I
try to execute the command

boxplot(Diatoms) (or for any other field instead of Diatoms)

I get the following error message:

Any advice would be much appreciated.

Thanks a lot,

[R] RES: WIERD: Basic computing in R

[Leandro Marino]

Hi,

the problem is what you want!

With the -2.7^8.6 you are doing -(2.7^8.6) it exists...

But, if you try (-2.7)^8.6 the R gives you NaN. When you define p=-2.7 and
q=8.6 and do p^q you are doing that (-2.7)^8.6.

If you write p=2.7 and q=8.6 and use the -p^q  it will work!

 R seems perfectly able to calculate -2.7^8.6, but fails when the exact
same values are assigned to variables and then the computation is repeated.
 Thanks in advance for any suggetsions.

Try

-(p^q)

Look at the code for the graphic on the R home page.
If you click on it you will see the code.

[R] RES: Change name of a specific column of a data frame

[Leandro Marino]

You can use names(database)[position]

where position is the number of the column that you want to rename!

Assunto: [R] Change name of a specific column of a data frame


Hi,

Sorry for the simple question. Is there a way to change the name of only one
column of an existing data frame?

I know colnames allows you to set the name of all the columns, but only one
column in the middle of my data frame needs a new name.

Thanks,
-Nina

[R] RES: Need ideas on how to show spikes in my data and how to codeit in R

[Leandro Marino]

Hi list,

I want to make a lot of graphics to my end course project. So, i was using
this sintax:


jpeg(filename = graf01.jpg, width = 1024, height = 1024,
 units = px, pointsize = 25, quality = 100, bg = grey95,
 res = NA, restoreConsole = TRUE)
i=1
par(mfrow=c(4,1),col=grey90,font.lab=2)
hist(sul[,i+2],nclass=75,xlab=Região
Sul,ylab=Freqüência,col=antiquewhite4,main=)
hist(PR[,i+2],nclass=75,xlab=Paraná,ylab=Freqüência,col=antiquewhite4,
main=)
hist(SC[,i+2],nclass=75,xlab=Santa
Catarina,ylab=Freqüência,col=antiquewhite4,main=)
hist(RS[,i+2],nclass=75,xlab=Rio Grande do
Sul,ylab=Freqüência,col=antiquewhite4,main=)
dev.off()

But, I want to know how can I create an for to do that. Like that:

for(i in 1:250){
jpeg(filename = graf01.jpg, width = 1024, height = 1024,
 units = px, pointsize = 25, quality = 100, bg = grey95,
 res = NA, restoreConsole = TRUE)
par(mfrow=c(4,1),col=grey90,font.lab=2)
hist(sul[,i+2],nclass=75,xlab=Região
Sul,ylab=Freqüência,col=antiquewhite4,main=)
hist(PR[,i+2],nclass=75,xlab=Paraná,ylab=Freqüência,col=antiquewhite4,
main=)
hist(SC[,i+2],nclass=75,xlab=Santa
Catarina,ylab=Freqüência,col=antiquewhite4,main=)
hist(RS[,i+2],nclass=75,xlab=Rio Grande do
Sul,ylab=Freqüência,col=antiquewhite4,main=)
dev.off()
}

The problem is the name of the file, I want to do something like grafi.jpg
where i goes from 1 to 250.

Thanks a lot for the help.


Best Regards,
Leandro Marino
