[R] Splitting a vector into equal groups
Hi All, I have vector of length 52, say, x=sample(30,52,replace=T). I want to sort x and split into five *nearly equal groups*. Note that the observations are repeated in x so in case of a tie I want both the observations to fall in same group. This seems a very common task to do, but still I couldn't find an R function to do this. Any help would be highly appreciated.

Re: [R] Splitting a vector into equal groups
check functions cut() and quantile(), and cut2() from package Hmisc; maybe the following is close to what you want: x - sample(30, 52, replace = TRUE) k - 5 # how many groups qs - quantile(x, seq(0, 1, length.out = k + 1)) y - cut(x, round(qs), include.lowest = TRUE) y table(y) I hope it helps.

The sum of the elements of the groups should be nearly equal? Note that the observations are repeated in x so in case of a tie I want both the observations to fall in same group. Then it becomes even more important to define what you mean with nearly equal groups. As a start, you may consider: R set.seed(1) R x=sample(30,52,replace=T) R xrle - rle(sort(x)) R xrle Run Length Encoding lengths: int [1:25] 2 1 2 2 3 1 1 1 5 1 ... values : int [1:25] 1 2 4 6 7 8 9 11 12 13 ...

E.g., should the first group have 10, 11 or 12 elements in this case? The information in xrle should enable you to construct your five groups once you have decided on a grouping. HTH.

Concrete: I will write some programs in R and want to execute this files outside of R, so I don't want to start R eyery time if i want an analysis. The best case were a surface of e.g. 8 Buttons, each click leads to start a specific R file. My outputs are JPEG or CSV, so I don`t need the output inside of R. Could anyone can give me some recommendations, what could be a solution (e. g. Java)? Is such a solution possible?

[R] levelplot question
Hi there, I have a question concerning the behaviour of the colouring with levelplot. (I hope, I manage to explain) If I give the parameters at and col.regions like this: at - c(1,2,3,4,5,6) col.regions - c(blue,blue,blue,yellow,yellow,yellow) Which color would have the value 3.5? I would have expected yellow, no? In my more complex example I wanted to create a heatmap (like yellow to red) up to a fixed threshold. All values above should get another color (like blue). Automatically, I generated both vectors like this: at -c(vectorOfLowerValues, myThreshold, vectorOfHigherValues) col.regions - c(vectorOfHeatmapColors, lastHeatmapColor, vectorOfColorblue) But I get some values above the threshold which are not blue... Can anybody explain me why? (I've checked the length of both vectors and it's parts - this is correct - so 'myThreshold' would get 'lastHeatmapColor' by the same vector position) I'm very confused...

Ctrl-L will do it. If you want to put it in a function, I don't think so.

Note that the same technique used to clear the screen could be used for

Re: [R] Caret package: coeffcients for regression
Alex, I am using Caretpackage for SVM regression and elastic net regression . I can get the final fiited vs observed values. How can I get the coefficients? Any ideas? You didn't say what version of caret and R you are using, what kernel or what type of coefficients. If you tune a model using train: fit - train(x, y, enet) then fit$finalModel contains an enet object with the final parameters. You can use coef() or any other appropriate function on this object. In the case of the elastic net, see ?predict.enet, specifically the type argument to get the regression coefficients. If you need to get to the final tuning parameters for the model, you can access them via x$finalModel$tuneValue. There are a few exceptions to this: models using S4 classes won't allow adding new objects. For SVMs, you haven't said what kernel type you used. caret uses kernel methods from kernlab (for no other reason that I like the package). The only package that I know gives the *regression* coefficients for linear kernels is svmpath (there could be others). If you want the SV coefficients (typically denoted by alpha), kernlab has a slot called coef that you can use. You should really provide more information for your questions to be answered well. -- Max __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Reply from Jeffery Horner contained links to the revolution-computing.com webpage which had information pertaining to the Bay Users R group Meetup on Web Dashboards with R. I have a very specific project that I need to implement. I wish to use the graphics capabilities provided by Adobe FLEX to visualise outputs from R. For example: I would like to fit a regression model to a dataset in R and provide a FLEX interface wherein, a user may manipulate a slider which would increase or decrease a parameter estimate (between the confidence intervals of the estimate) of a variable to see the effect on the predicted values. I necessarily have to use FLEX for the interface. In trying to make sense of how to go about this task, I have speculated on the following technologies: 1) Using RSOAP which requires a Python client. I am not sure how I can implement this in Flex. 2) Using RSOAP provided by the Biocep project. This is a java implementation and maybe this would suit my requirements. 3) The StatDataML package in R provides the creation of xml files of R objects. Maybe I can use these XML files as encapsulators of R object data and pass it on to FLEX. 4) Since R has interfaces that connect to most SQL database servers, I can convert results of lm objects (summary(lmobject)) to data frames and push them into the SQL database.

Re: [R] can install.packages() copy utility files to the public_html directory ?

Re: [R] Surface for R outside of R
Hi Koj, I just completed a Windows application using the batch approach and it works very well. In our case, we used VBA for Excel to call different batch files that execute R code, but you can do the same from any platform. Here is a simple step-by-step example on how to make the batch files work (in Windows): 1. Write your R code and save it the directory where you want your results. Here is a very simple example using a file called normal.r. This code takes 100 random samples from a standard normal and writes the results to a file called data.txt write(rnorm(100),data.txt) q(save=no, runLast = F) 2. Make sure that the console finds the path to R without changing your path environment variable. The easiest way to do this is to download the batchfiles that Gabor Grothendieck has kindly provided in this site http://code.google.com/p/batchfiles/ and put one or all of the files in the same directory where your batch and R files will reside. The only file I have needed so far in different WinXP and Vista machines was Rcmd.bat but you may need to use others. 3. Open a text editor and create a file with a .bat or .cmd extension. Here is an example of a file called TestBatch.CMD that runs the code in normal.r @ECHO OFF title Random number generation ECHO Taking 100 random samples from a N(0,1) Rcmd BATCH --slave normal.r Log.txt ECHO Analysis done. See the file data.txt for results PING 1.1.1.1 -n 1 -w 1000 NUL @ECHO OFF The main line here is Rcmd BATCH --slave normal.r Log.txt which tells the console to run your R code, and to write outputs printed in the console (i.e. errors) to the Log.txt file. The PING argument adds a short lag before the console closes, so the user can see what is echoed in the console. The other lines should be pretty self-explanatory. 4. Execute the TestBatch.CMD file (by hand or via your GUI) and watch the results. You should now see two new files (data.txt and Log.txt) in the same directory as the batch file. I hope this helps. Let me know if you have any other questions. Regards, Francisco Francisco J.

[R] [R-pkgs] frontier 0.99 is NOT backward compatible
Dear current (and future) users of the frontier package, We are approaching the first stable version (1.0) of the frontier package, which provides tools for microeconomic Stochastic Frontier Analysis (SFA). I have uploaded a kind of beta release (version 0.99) of this package to CRAN. The most important differences to version 0.9 affect the user interface. I have modified the package so that it is (hopefully) simpler to use and the functions are more similar to other R functions. Unfortunately, these changes make the new version NOT backward compatible. The most significant changes are reported below. A full ChangeLog is available in the log messages of the SVN repository on R-Forge [1]. Feedback about this package is highly appreciated. Please report any bugs, suggestions, feature requests, comments, and questions in the forums and trackers on R-Forge [1]. [1] http://r-forge.r-project.org/projects/frontier/ Best regards, Arne CHANGES IN VERSION 0.99-0 * corrected and considerably improved documentation of function fontier * changed order of arguments of function frontier * removed arguments crossSectionName and timePeriodName from function frontier: in case of cross-section data, these variables (information) are not needed, and in case of panel data, the information on the panel structure has to be added to the data set by the function plm.data of the plm package * argument modelType of function frontier must be ECF or EEF now * replaced argument funtionType of function frontier by argument ineffDecrease * renamed argument eta of function frontier as timeEffect * split argument mu of function frontier into truncNorm and zIntercept * increased default value of argument maxit of function frontier to 1000 * renamed argument step1 of function frontier as searchStep * renamed argument tol2 of function frontier as searchTol * replaced argument indic of function frontier by searchScale * renamed argument gridno of function frontier as gridSize * renamed argument igrid2 of function frontier as gridDouble * renamed argument iprint of function frontier as printIter * removed arguments qxNames and quadHalf from function frontier, because quadratic or translog frontiers can be estimated with function frontierQuad now * added logLik method for objects of class frontier * added function frontierQuad for estimating quadratic and translog frontiers * added function frontierTranslogRay for estimating stochastic ray translog frontier functions * added the generic function efficiencies and corresponding methods for default objects and objects of class frontier * added elas method for objects of class frontierQuad * function frontier() and frontierQuad() return the (matched) call now * the matrix of efficiency estimates returned by frontier has row names (cross section units) and possibly column names (time period) now -- Arne Henningsen http://www.arne-henningsen.name/ ___ R-packages mailing list r-packa...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] Surface for R outside of R
Also see Rscript.bat in the same batchfiles distribution. It automatically finds Rscript.exe by looking in the registry in the same way that Rcmd.bat finds Rcmd.exe. On Mon, May 4, 2009 at 2:43 PM, Francisco J. Zagmutt gerifalt...@hotmail.com wrote: Hi Koj, I just completed a Windows application using the batch approach and it works very well. In our case, we used VBA for Excel to call different batch files that execute R code, but you can do the same from any platform. Here is a simple step-by-step example on how to make the batch files work (in Windows): 1. Write your R code and save it the directory where you want your results. Here is a very simple example using a file called normal.r. This code takes 100 random samples from a standard normal and writes the results to a file called data.txt write(rnorm(100),data.txt) q(save=no, runLast = F) 2. Make sure that the console finds the path to R without changing your path environment variable. The easiest way to do this is to download the batchfiles that Gabor Grothendieck has kindly provided in this site http://code.google.com/p/batchfiles/ and put one or all of the files in the same directory where your batch and R files will reside. The only file I have needed so far in different WinXP and Vista machines was Rcmd.bat but you may need to use others. 3. Open a text editor and create a file with a .bat or .cmd extension. Here is an example of a file called TestBatch.CMD that runs the code in normal.r @ECHO OFF title Random number generation ECHO Taking 100 random samples from a N(0,1) Rcmd BATCH --slave normal.r Log.txt ECHO Analysis done. See the file data.txt for results PING 1.1.1.1 -n 1 -w 1000 NUL @ECHO OFF The main line here is Rcmd BATCH --slave normal.r Log.txt which tells the console to run your R code, and to write outputs printed in the console (i.e. errors) to the Log.txt file. The PING argument adds a short lag before the console closes, so the user can see what is echoed in the console. The other lines should be pretty self-explanatory. 4. Execute the TestBatch.CMD file (by hand or via your GUI) and watch the results. You should now see two new files (data.txt and Log.txt) in the same directory as the batch file. I hope this helps.

[R] to the person who asked about dividing by the base row
to whomever that was. i deleted your email but I think below does what you
want. as always, there's probably some
improvement that could be done. whether it's  minor or major, i'm not sure
?
also, 3 things:Â Â
A)there are some Inf's in the output because of division by zero but I
wasn't sure how you wanted to handle that.
B) it also assumes that an n=1 always exists and you should probably have
some error checking in there for when it doesn't.Â
C) When i tried to condense it to below, I got an error that division is
only valid for equal sized data frames and
I'm not sure why so maybe someone can say something about that ?

[And a lot of other variables, and sp also changes]
Now, I want to divide each of the v.* variables for every (sp, wg, n)
combination by the values in the row defined by (sp, wg, 1), thus giving
a relative change to the case n==1 for the same combination of sp and wg.
I have written the following function, but I'm wondering whether there's
an easier/more efficient way.. Perhaps by organizing the data structure
differently, and if so -- how?
speedup.1 - function(df)
{
groups - split(df, df[,c(sp,wg)])
ret - list()
for(g in groups) {
ref - g[1,]
for(v in 4:15) # sp,wg,n are factors, so / doesn't work..
g[[v]] - ref[[v]] / g[[v]]
ret - rbind(ret, g)
}
ret
}

Re: [R] can install.packages() copy utility files to the public_html directory ?
Markus Loecher wrote: Dear fellow R-users, I am about to publish an HTML utility package to CRAN that expands on the R2HTML package and includes a few goodies such as sorted tables, easy automation of framed HTML reporting, etc. However, some of the resulting dynamic HTML pages need to access JavaScript code that should sit in a specific subdirectory of public_html. My more general question is hence, (i) how do I include the directory containing the JavaScript code in my R package and Yes, in directory ./inst/JavaScript for example that is copied to ./JavaScript during installation of the package. (ii) is it possible to copy this directory to the user's public_html path during installation ? Yes, if it is a source package (not for a binary package), BUT you should not write such code that copyies files to a directory different than the package's directory in the library that it is installed to.

Re: [R] Optim function in the loop
Thanks for the reply.
optim(initpar,Linn,NULL,method=BFGS,hessian=TRUE,control=list(trace=1,REPORT=1,maxit=300))
The optim is to minimize the negative likelihood function which is performed
in function Linn,
Every time the code stops right after optim, for example, the output looks
like:
iter 16 value 42.818394
iter 16 value 42.818394
final value 42.818394
converged
It seems from the code that the loop should continue to run, at least
calculate u values... but it does not...
Thank you.

[R] questions about function arima0
Hi, I work on order estimation for autoregressive processes and after some inconsistencies cropped up I implemented the AIC criterion myself. Its results do not match the implementation in R and there are a few things I can not understand even after reading the source code of R. I used the function called arima0 (with empty ma coeficient vector), and I do not understand how some of the results are calculated: 1. resid If we denote the estimated order of a time series by k, how does the function calculate the first k elements of the residual vector? The rest of the elements match my version, but the first k are not calculated in my implementation. Calculating them requires some kind of assumption, but after trying a few possible ones (like using zero in place of the missing elements ot the average of the time series) none of them seem to yield the same results as I get from arima0. 2. loglik The loglikelihood at it's maximum should be a funcion of the estimated residual variance if the residuals are assumed to be normally distributed: -2*loglik = n*log(sigma2)+n*log(2*pi)+n The $loglik and $sigma2 variables from arima0 do not satisfy that equation. In my implementation I calculated the residual vector the same way, but leaving the first k elements, then calculating sigma2 by sum(resid^2)/(n-k), and at the end I got the loglikelihood through the equation above. If I compare the Akaike information criteria I get from my implementation to the one of R's, I get quite different results. I performed 100 simulations with time series of length 1000 and the ratio of correct order selection was different (lower with my implementation than with R's). Can you help me to find out what causes the difference?

Re: [R] FOURIER INTEGRALS IN R
integrate offers some one-dimensional algorithms, but you need to start with a smooth function to get it to converge properly. With a cosine integral, there may be certain routines that offer better value for money: the Clenshaw-Curtis integration, or perhaps the FFT. You would have to recast your problem by doing some sort of substitution. Perhaps post some latex code to show the exact type of integral you are wanting to calculate.

Just curious about how to handle this, and if read.table is the right way to go about or if I should read in all the data and then try to parse it out best I can. Thanks again.

Re: [R] Way to handle variable length and numbers of columns using read.table(...)
Well if you read in your data, you get:

$ Loc2: num 44.5 89 NA 89
As you can see the variable that has two decimal points is read in as a
character and cause the whole column to be converted to a factor. It
appears that you have some fixed length fields that are overflowing. Now
you could read in the data and use regualr expressions and parse the data;
you just have to match on the first part have two decimal place and then
extract the rest. THe question is, is this the only problems you have in
the data? If so, parsing it is not hard.

Avg. Loc1 = 77.88
Avg. Loc2 = 55.66
Final Time = 4
Right now I am using nrows in order to only read Time 1-4 skip to skip
over the unusable header info, e.g.
read.table(read.table('clipboard', header=FALSE, fill=TRUE, skip=5, nrows=4)
Unfortunately, sometimes the number of Time rows varies, so I need to also
account for that.
Maybe I need to look into what Gabor suggested as well, i.e. library(gsubfn)
Thanks again for any feedback and advice on this one, as the data I receive is
out of my control, but I am working with the go get them to fix it as well.

Well if you read in your data, you get:
x - read.table('clipboard', header=TRUE,
fill=TRUE)
Warning message:
In read.table(clipboard, header = TRUE, fill =
TRUE) :

str(x)

$ Loc1: Factor w/ 3 levels
22.33,222.33344.55,..: 1 3 2 3
$ Loc2: num 44.5 89 NA 89
As you can see the variable that has two decimal points is read in as a
character and cause the whole column to be converted to a factor. It appears
that you have some fixed length fields that are overflowing. Now you could
read in the data and use regular expressions and parse the data; you just have
to match on the first part have two decimal place and then extract the rest.
THe question is, is this the only problems you have in the data? If so,
parsing it is not hard.

Is there any way to have read.table handle (1) a
variable number of rows,
and (2) sometime there are only two variables as shown

Just curious about how to handle this, and if
read.table is the right way
to go about or if I should read in all the data and
then try to parse it out
best I can.
Thanks again.

Re: [R] Way to handle variable length and numbers of columns using read.table(...)
The last line should be as follows (as the previous post missed the time column). The regular expression says either start from beginning (^) and look for a string of digits, [0-9]+, or look for digits [0-9]*, a dot [.] and two more digits [0-9][0-9]. Each time strapply finds such a match as.numeric is applied to it. Thus line of input results in a numeric vector and then we simplify those vectors by rbind'ing them together. strapply(L[-1], ^[0-9]+|[0-9]*[.][0-9][0-9], as.numeric, simplify = rbind) [,1] [,2] [,3] [1,]1 22.33 44.55 [2,]2 66.77 88.99 [3,]3 222.33 344.55 [4,]4 66.77 88.99 On Mon, May 4, 2009 at 11:04 PM, Gabor Grothendieck ggrothendi...@gmail.com wrote: Its not clear exactly what the rules are for this but if we assume that numbers always end in a decimal plus two digits then using stapply from the gsubfn package: Lines - Time Loc1 Loc2 + 1 22.33 44.55 + 2 66.77 88.99 + 3 222.33344.55 + 4 66.77 88.99 library(gsubfn) L - readLines(textConnection(Lines)) strapply(L[-1], [0-9]*[.][0-9][0-9], as.numeric, simplify = rbind) [,1] [,2] [1,] 22.33 44.55 [2,] 66.77 88.99 [3,] 222.33 344.55 [4,] 66.77 88.99 See http://gsubfn.googlecode.com and for regular expressions see ?regex On Mon, May 4, 2009 at 10:20 PM, Jason Rupert jasonkrup...@yahoo.com wrote: I've got read.table to successfully read in my table of three columns.
