Re: [R] Likelihood optimization numerically

2008-01-27 Thread Mohammad Ehsanul Karim
Dear List,

Probably i am missing something important in optimize:

llk.1st - function(alpha){
x -  c(20.0, 23.9, 20.9, 23.8, 25.0, 24.0, 21.7, 23.8, 22.8, 23.1, 23.1, 23.5, 
23.0, 23.0)
n - length(x)
llk1 - -n*log(gamma(alpha)) - n*alpha*log(sum(x)/(n*alpha)) + (alpha - 
1)*(sum(log(x))) - (sum(x))/(sum(x)/(n*alpha))
return(llk1)
} 

plot(llk.1st, 1,1000)
optimize(f=llk.1st, interval =c(0,1000), tol = 0.0001)


Reported result is approximately -
alpha = 500
beta = 0.05

But i get -
$minimum
[1] 1000 ## whatever the upper bound is!!
$objective
[1] -Inf
There were 50 or more warnings (use warnings() to see the first 50)

also,
 optim(par = 500, fn = llk.1st)
Error in optim(par = 500, fn = llk.1st) : 
  function cannot be evaluated at initial parameters
In addition: Warning messages:
1: In optim(par = 500, fn = llk.1st) :
  one-diml optimization by Nelder-Mead is unreliable: use optimize
2: In fn(par, ...) : value out of range in 'gammafn'


Can 
anyone 
provide

hint?

[R] OR estimate

2008-01-27 Thread sigalit mangut-leiba
Hello,
I have a loop with 1000 repetitions which includes OR computation of an
exposure factor and outcome.
I compute OR like this:

t-table(exposure,outcome)

oddsratio(t)$measure[estimate]

This gives me the estimates for exposure=0 and exposure=1 but exposure=0 is
the reference group and i need only the estimate for exposure=1.

I specified a matrix OR with 3 columns (for OR estimate and lower and upper
confidence limits) and 1000 rows

OR[k,]-oddsratio(t)$measure[estimate]?

I tried: exposure==1 or measure[estimate] and it gives me missing
value NA.

I appriciate any help,

Sigalit.

 But I still get x ticks at 1, 1.5, 2, 2.5, 3 on both x and y axes. I
 thought lab
 controlled this (according to the documentation).

 What am I doing wrong, or is there some restriction on the way the
 function works?
 I don't know the answer about scatterplot3d, but you can get
 approximately what you want with the rgl package using


plot3d(mymat,
  type=h,
  xlab=xlabel, ylab=ylabel, zlab=zlabel,
  xlim=c(1,3), ylim=c(1,3),
  size=5,
  axes=FALSE,
  main=My Bar Plot)

  axis3d(x, at=1:3, labels=c(Low,Medium,High))
  axis3d(y, at=1:3, labels=c(Green,Blue,Black))
  grid3d(z, n=3)
 
 I couldn't install rgl due to the following problems:
 
 g++ -I/usr/local/lib/R/include -I/usr/local/lib/R/include -DHAVE_PNG_H
 -Iext -I/usr/local/include-fPIC   -c par3d.cpp -o par3d.o

 make: *** [par3d.o] Error 1
 chmod: cannot access `/usr/local/lib/R/library/rgl/libs/*': No such

 ERROR: compilation failed for package 'rgl'

I think you're not using R 2.6.x or later, which has a different 
signature in psmatch.  But I didn't realize changing rgl to match the 
new one would make it incompatible with older ones.  You should be able 
to get rgl version 0.75 to compile.

 But Uwe's suggestion with scatterplot3d gives a better result than I had.  
 But I
 might use multiple 2d plots instead.
 
 Many thanks,
 
 Geoff.
 
 
 
 You might prefer to change the mouse controls to

  par3d(mouseMode=c(zAxis,zoom,fov))

 so that the main mouse button does rotation about the vertical axis,
 rather than completely general rotation.

 hi Gabor and Duncan,
 
 I make a test and I find that the key of problem

 I don't understand this behaviour yet! :-(

I understand it now.  It's a small bug in the startup code.

When you specify a file to restore on the command line, it has two 
effects:  it changes the working directory to the directory of that 
file, and it loads the file.  Unfortunately, the code that loaded the 
file assumed it was in the current directory and used a relative 
filename, not an absolute path.  (I think this was due to workarounds 
for behaviour of old Windows versions that are no longer supported.)

When your Rprofile.site file changed the working directory, R tried to 
load the test.RData file from there, and failed.  So you didn't get what 
you wanted.

I'll fix this in R-devel and R-patched, and it should make it into the 
next release.

 then ggplot - good work.

 My problem is that I am using facet_grid() in the following way:

   p - ggplot(ssq, aes(x=year, y=-log(ssq)))
   p + geom_point() + facet_grid(me*gi~cs*rz)

 and it works nicely, except that I would like to have, in naddition to
 the values of me, gi, cs and rz the name of the variable. I.e: if gi is
 1, 2 and 3 I would like to have gi = 1:, gi = 2 and gi = 3 as
 labels of the p[anels. I did it with ggplot, but I don't remember and I
 have lost the code ...

ggopt(strip.text = function(variable, value) paste(variable, value, sep== ))

 Just a small comment on the package: as I am using emacs with ess, I
 have to press _ twice to get the underscore in the commands (as the
 first one is replaced with - and then reverted to _) - would it be
 possible to change these in the next release with . (but still provide
 an alias with _)?

I know it's a pain but I think emacs users need to change their ways
(and default settings) because as time goes by I think you'll see
increasing numbers of packages using _ instead of . to prevent
conflicts with S3.  It would be nice if R had a standard convention
for separating words in functions.

Re: [R] Putting frame around single panels in ggplot 2 and facet_grid()

What about using geom_vline and geom_hline to draw

intercept max value for geom_vline and hardcoded it to
5.5

d- ggplot(mtcars, aes(x=mpg, y=wt)) + geom_point()  +

  Hi
 
  I want to highlight two panels in a grid created
 with facet_grid() by
  putting a box around it or usiong another
 background colour. Is this

 It's possible, but not particularly easy.  You could
 do something like:
 
 # Background colours
 background - data.frame(
   cyl = c(4, 6, 8),
   fill = c(NA, alpha(red, 0.2), alpha(black,
 0.3))
 )
 
 # Points defining square region for background
 square - with(mtcars, data.frame(
   x = c(min(mpg), max(mpg), max(mpg), min(mpg)),
   y = c(min(wt), min(wt), max(wt), max(wt))
 ))
 
 ggplot(mtcars, aes(x=mpg, y=wt)) +
 geom_polygon(aes(x=x,y=y, fill=fill),
 data=merge(background, square)) +
 geom_point() +

[R] Data manipulation question (opposite of table?)

2008-01-27 Thread Michael Denslow
Dear R users,

I am a new user (probably obvious by my question) and
have really learned a lot from reading this list.
Thank you all very much. My main struggles with R are
with data manipulation.

So here is my question...
I have data that is organized as below, this is a
short example.

value count
1123225
1588524
2246420
etc...

the 'value' field is distances and the 'count' field
is the number of times that each distance occurs. So I
guess it is in the same format as the output for the
table() function.

What I need to do is make one long vector (or list)
that includes all the actual numbers. In other words
11232 listed 25 times followed by 15885 listed 24
times etc. etc.

Thank you again in advance,
Michael

Perhaps there are other opinions, but from my point
of view R is spectacularly similar in Linux and Windows
(and will be virtually identical in Linux and Unix).  As
long as you are doing R things, you should be in home
territory.

I regularly transfer R objects between 64-bit Linux and
Windows, and have never had any problems.

It has always been faster in Linux than in Windows on the same hardware. 
In addition, the toolchain issues have been holding up 64 bit

Dear R-Users,

as I will start a huge simulation in a few weeks, I am about to buy a new

many of my calculations up to now (I had 2 GB in my old system, but
Windows still used quite a lot of virtual memory), hence my new computer
will have 4 GB of fast DDR2-800 RAM.

However, I know that 1.) Windows 32 bit cannot make use of more than about
3,2 GB RAM and 2.) it is normally not allowed to allocate more than 2 GB
  

of
  

RAM to one single application (at least under XP, I don't know if that has
changed under Vista?).

I remember from the R-FAQ that you can manually adjust XP so that it
allocates up to 3 GB to one application (the 3GB patch), but I read in a
PC-magazine and some message boards that this may cause problems. Does
anybody of you successfully use this trick without any problems?

  

Yes, many people: most 32-bit Exchange servers use it.  Please don't rate
the advice in the R documentation below tittle-tattle you read on the web.

  


Would it be wise to use a 64bit OS, as e.g. Vista X64? I think, under
  

Vista
  

X64 it should be no problem to allocate 4 GB of RAM to R. Any experiences
with that?

  

That's what the rw-FAQ says, and we do write answers based on experience!

Re: [R] Linux, UNIX, XP32, Vista X64 or ...? [SEC=UNCLASSIFIED]

2008-01-27 Thread Gabor Grothendieck
On the PC there is a builtin GUI but not on UNIX and there are
some packages that are OS specific in which case you might
get more or less selection but probably more.  Also depending
on the specific system you may have greater difficulty installing
certain packages due to the need to compile them on UNIX
and the possibility exists that you don't quite have the right
libraries.  On Windows you get binaries so this is not a problem.
I have repeatedly found that common packages that I took
for granted on Windows had some problem with installation
on UNIX and I had to hunt around and figure out what the problem
was with my UNIDX libraries or possibly some other problem.
For all R packages this won't be a problem but for packages
that use C and FORTRAN this can be.  Although I am lumping
all UNIX systems together I think this varies quite a bit from
one particular type/distro of UNIX/Linux to another and I suspect if you
are careful in picking out the right one (if you have a choice) you
will actually have zero problems.

  Dear R-Users,
 
  as I will start a huge simulation in a few weeks, I am about to buy a new

  Windows still used quite a lot of virtual memory), hence my new computer
  will have 4 GB of fast DDR2-800 RAM.
 
  However, I know that 1.) Windows 32 bit cannot make use of more than about
  3,2 GB RAM and 2.) it is normally not allowed to allocate more than 2 GB of
  RAM to one single application (at least under XP, I don't know if that has
  changed under Vista?).
 
  I remember from the R-FAQ that you can manually adjust XP so that it
  allocates up to 3 GB to one application (the 3GB patch), but I read in a
  PC-magazine and some message boards that this may cause problems. Does
  anybody of you successfully use this trick without any problems?

 Yes, many people: most 32-bit Exchange servers use it.  Please don't rate
 the advice in the R documentation below tittle-tattle you read on the web.

  Would it be wise to use a 64bit OS, as e.g. Vista X64? I think, under Vista
  X64 it should be no problem to allocate 4 GB of RAM to R. Any experiences
  with that?

 That's what the rw-FAQ says, and we do write answers based on experience!

  Thanks in advance,

[R] Package simex

2008-01-27 Thread Michael Kubovy
Dear R-helpers,

It is not clear to me how you get measurement.error SD when you have a  
single dataset, and it is not clear to me how sensitive SIMEX is to  
errors in the estimates of measurement error.

Could someone please point me to the relevant literature?

[R] How to fill bar plot with textile rather than color

2008-01-27 Thread CHENYS

Hi, I'm looking for a tool which can fill bar chart with dash, skewed line,
or grids, rather than pure color. Any one have the idea how to do that in R?
Or maybe in Matlab will also be helpful.

Thanks very much.

[R] Package Installation produces gcc fails sanity check error when installing RODBC error

2008-01-27 Thread Joe_K

Dear Friends,

I haven't used R very much, but am hoping to use it more.  I recently
installed it again on my Linux machine and began to install a few packages,
which I figure I will need.  I am also new to this forum.  I hope I am
posting it in the right place.

I am trying to install a few packages in R and am receiving error messages. 
Since the error messages are different for each install package request, I
am posting them separately.  The first error is with the installation of
RODBC.  I suspect the problem is with how the R package installer interfaces
with gcc.

The basic error message is:


gcc -std=gnu99 -E
configure: error: C preprocessor gcc -std=gnu99 -E fails sanity check
See `config.log' for more details.
ERROR: configuration failed for package 'RODBC'

See below for full output

I have been Googling the issue all weekend and have found similar errors,
but not exactly the same.  Several of the responders to these error help
requests suggested that they install additional software, which I already
have.

The following relevant software is installed on the machine:

with 4Gb Ram and 2 dual CPUs (total of 4 CPUs).  The CPUs are AMD Opteron. 
Hard Disk Usage is 4 150 Gb SATA drives array with a Com3 9550SX Controller

Initially I tried installation through Rkward, but also tried from the R
command prompt as well.  Rkward provides more verbose error reporting. 
Below is the full output when I attempt to install the package through

Thanks for your help,

[R] Package Installation produces linux/limits.h: No such file or directory error when installing the lpSolve package

2008-01-27 Thread Joe_K

Dear Friends,

I am trying to install a few packages in R and am receiving error messages. 
Since the error messages are different, I am posting them separately.  The
second error is with the installation of lpSolve.

The core error message is:

In file included from /usr/include/bits/posix1_lim.h:153,
 from /usr/include/limits.h:145,
 from
/usr/lib64/gcc/x86_64-suse-linux/4.2.1/include/limits.h:122,
 from
/usr/lib64/gcc/x86_64-suse-linux/4.2.1/include/syslimits.h:7,
 from
/usr/lib64/gcc/x86_64-suse-linux/4.2.1/include/limits.h:11,
 from colamd.c:677:
/usr/include/bits/local_lim.h:36:26
 error: linux/limits.h: No such file or directory
make: *** [colamd.o] Error 1
ERROR: compilation failed for package 'lpSolve'


The first things that I tried was to figure out where linux/limits.h was.  I
discovered that there are seven versions of limits.h on the system and they
are not identical.

/usr/include/limits.h
/usr/src/linux-2.6.22.13-0.3/Documentation/i2c/chips/limits.h
/usr/include/c++/4.2.1/tr1/limits.h
/usr/lib64/qt4/demos/qtdemo/xml/limits.h
/usr/src/linux-2.6.22.13-0.3/include/linux/limits.h
/usr/src/linux-2.6.22.13-0.3/include/asm-arm/limits.h
/usr/src/linux-2.6.22.13-0.3/include/asm-arm26/limits.h

Only one has linux immediately preceding it in the path:
/usr/src/linux-2.6.22.13-0.3/include/linux/limits.h

I assume that /usr/include/bits/local_lim.h is trying to use a relative
path.  The only line in local_lim.h with limits.h in it is:

#include linux/limits.h

So, I tried modifying the line to read:

#include /usr/src/linux-2.6.22.13-0.3/include/linux/limits.h

That did not work, so I changed it back again.  I guess my theory about it
looking for a relative path was wrong.

Since then, I have been Googling the issue all weekend and have found
similar errors, but not exactly the same.  Some are suggesting changing
kernel headers and other files.  Since the context of these other posts are
dissimilar, I figured it best not to mess with kernel headers or some of the
other radical solutions offered.

There was one suggestion in a post to install glibc-headers, however, I
cannot seem to find that for Suse 10.3.  Is it something included in another
package?  Is it something that is now obsolete?

CAN ANYONE HELP ME DEBUG THIS?

[R] R command line usage

2008-01-27 Thread Deepak Chandran
Hello,
   
Usually if I want to run R code from another program, I generate an 
R script and run R BATCH. However, I have been wanting to access R's 
command line from another program. In other words, I want the std output 
from another program to feed into R (command line). Is there any way to 
do that? I would also like to collect R's response using std input.

Thanks

[R] How to read Directory

2008-01-27 Thread Prateek Singh
Hi,

I have bunch of files to be parsed for my problem. I don't want to
keep on executing R script for each file.
Is there any way through which I can read whole directory. Like PERL
has opendir() function for directory handling.

One more doubt is commandArgs() function returns array  or single
variable. How exactly we should give command line argument.



Regards,
Prateek

Is ?dir or ?list.files what you need?
