I would also love to see this implemented in R, as my current solution to the issue of doing tons of open/close, dev/dev.off, etc. is to use snippets in my IDE, and in the end I feel...

This is not very informative. What exactly is crashing? What is your sessionInfo() output? On Thu, May 12, 2011 at 7:57 AM, Bazman76 <h_a_patience at hotmail.com> wrote: > OK I did a seach for the files and...

I would recommend trying to fix the installation of R 2.13.0 rather than trying to obtain old packages. Try downloading the installer again from a different mirror. On Thu, Jun 2, 2011 at 10:33 AM, jmdpulido <jmdpulido...

See packages rpart, randomForest, party. Also, typing "R Decision Trees" produced good google results. http://www.google.com/search?aq=f&sourceid=chrome&ie=UTF-8&q=R+Decision+Trees On Wed, Jun 8, 2011 at 7:02 AM, stefan...

OK, Assume all your trap names are stored in a vector trap.names. Does: sapply(trap.names, FUN = function(x) { tmp. <- outer(release.days[Trap==x],collection.days.2[Trap==x],'-') tmp <- ifelse(temp.ACAP1>=0,NA,temp.ACAP1) return...

Does this work for you? which(is.nan(mat1 %% mat2), arr.ind = T) On Tue, May 31, 2011 at 10:52 AM, Alaios <alaios at yahoo.com> wrote: > Thanks alot. > Unfortunately I can not apply this to much bigger matrices...

Save it anywhere that is on your search path, which can be seen by typing path into the command line. On Tue, May 24, 2011 at 12:40 PM, Muhuri, Pradip (SAMHSA/CBHSQ) <Pradip.Muhuri at samhsa.hhs.gov> wrote...

Hi Ben, Unfortunately, I left the usb cable for my crystal ball at home, and thus have no idea how your data is organized. Could you post an example along with what you expect the output to be? Jon On...

One difference between colour and fill can be demonstrated by specifying both with different values. In cases where a polygon is filled, colour specifies border line color. On Mon, Jun 6, 2011 at 9:49 AM, wwreith <reith_william at...

My suggestion, since bold doesn't show up in a text only mailing list, would be to look into the function ?aggregate. It looks like something like (assuming your data is in a mydat): mydat.new <- aggregate(cbind(STN_ID...

Some good tcltk examples can be found online [1]. I have also found the fgui package on CRAN [2], though I have not actually used it yet. [1] http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ [2] http://cran.cnr.berkeley...

It is actually possible and preferable to do this with no loops. Assuming your data is in a dataframe called dat: idx <- with(dat, Site == 1 & Prof == 1) dat <- within(dat, { new = H - ifelse(Site == 1 & Prof == 1, min(H...

Does this work for you? dat <- lapply(c('EMAX','EC50','KOUT','GAMMA'),function(x)confint(lm(get(x)~RR0,dataset2))) names(dat) <- c('EMAX','EC50','KOUT','GAMMA') On Fri, May 27, 2011 at 10:03 AM, Jun Shen <jun.shen...

Java uses "heap space" when creating new objects. My guess is that since the default size is 128 Mb iirc, you are reading in an object larger than this. I don't know the guts of the xlsx package or...

The message is pretty clear. Access denied means you don't have permission to access the path. This also explains why the packages fail to load - you don't have access to R's package library. It most likely works...

So you need to read a file into R in that format? Try changing the values in ?read.table. Using the example, I was able to get the data using: read.table("clipboard", sep = "=", header = F, colClasses = c("character", "numeric...

In cases where I have to parse through large datasets that will not fit into R's memory, I will grab relevant data using SQL and then analyze said data using R. There are several packages designed to do this...

I would caution against using attach(), however, if you are not in an interactive session. In functions and scripts, errors can often cause the interpreter to exit before the detach(), leaving your data on the search path. 99% of all...

It looks like your call: lms.ASP[1,1] <- list(surf105.lm.ASP) makes a list of length 1 containing the lm object and puts that list into element [1,1] of your array. That is why you will need...

This is a very open ended question that depends very heavily on what you are trying to do and how you are doing it. Often times, the bottleneck operations that limit speed the most are not necessarily sped up by...
