Dear list, I gave up trying to fix my movie3d (rgl library) issue in my PC (completely black gif/png file) and went ahead and installed MacPorts and ImageMagick onto my iMac (OSX ver 10.6.8). I think ImageMagick is successfully installed in its default location (under /opt/local), and I ran movie3d but I get the following error: Error in system("convert --version", intern = TRUE) : ?

Dear list, I have been using multivariate multiple regression (MMR) in the form lm(Y~X) where Y and X are matrices of response and predictor variables. I know that summary(mlm.object) would give the usual lm statistics for each response variable separately and that anova.mlm(mlm.object) will give the analysis of variance table of the mlm object. However, anova.mlm (also manova(mlm.object))

Dear list, I have a matrix Y of multiple response variables and a matrix X of predictor variables and I would like to fit a multivariate multiple regression model and compute the R2-value to determine the overall proportion of variance of the response matrix Y that is explained by the predictor matrix X. I have been using manova(Y ~ X) to assess the significance of the linear model. I am also

Hello. Is there a package or functionality available somewhere which will allow for complex searches (such as what SQL can do) of collections of RData files? Search capability within a given RData file at a time (which could be put in a loop) would be good, but the capability to perform joins to data across multiple RData files would be great. These queries might be ad-hoc, so writing an R program

Hi, I discover that when I save a workspace containing a genefilter (pkg from Bioconductor) object I cannot open no more after. I have to restore the .RData file from a backup to be able to start R again. I didn't upgrade to Version 2.2 but I'm not sure that it will solve the problem. Did anyone have encounter the same problem? Below is a short r session to reproduce the error: ...

Dear All, I want to change file names. I have file0.1_data.RData (I have several files whose names are file0.x_data.Rdata) I want to rename it to file1_data.RData How can I do it? Thank you for saving my time! [[alternative HTML version deleted]]

If x has an S3 class then sort.int(x) returns a value without an S3 class but which has the is.object flag set, which, I think, causes identical() give a false/misleading report: > x <- structure(1:3, class="unrecognizedClass") > y <- sort.int(x) > t <- 1:3 > identical(y, t) # expect TRUE [1] FALSE > identical(as.vector(y), as.vector(t)) # expect

I've just had an interesting thing happen to one of our students. He's using R 1.9.1 on Linux, and so I dont expect bugfixes, I'm just reporting this out of interest in case anyone else has had this happen. Starting R caused a seg fault shortly after "[Previously saved workspace restored]". Running "R --no-restore-data" worked fine so I suspected a corrupted

Saving Rdata files in a zip archive form can in some cases save a considerable amount of disk space. R has the zip.file.extract function to extract files from zip archives, but appears not to have any corresponding function to save in zipped form. (At least I have not been able to find anything in the help files or through searching the mail archives.) The system function can be used to call gzip

Hi all, After a short hiatus away from R I have found that it's changed a bit. I used to keep a definition of .First in .Rprofile that did a couple of things on startup (load a couple of libraries). Now, I've discovered that when I change the definition of .First in .Rprofile it doesn't change anything when I start up, because .First is held over in .Rdata from the last session.

Dear R developers, i would like to start R with a *.RData argument under Linux. Something like R -f /home/user/workspace.RData Is this possible? Thanks in advance for any answers. -- View this message in context: http://www.nabble.com/Execute-R-with-*.RData-argument-tp16323374p16323374.html Sent from the R help mailing list archive at Nabble.com.

Dear all, I have a version 1.3.1 of R which is under Linux Redhat. I have worked with it without any problem. But now when I try to run R, I get the error message as follows : Error: an xdr real data read error occured Fatal error: unable to restore saved data in .RData Thank you in advance and sorry if my question is perhaps simple.

Colleagues: I am having trouble loading data from within .Rdata file within the environment of a function. That is, the following always loads to the global environment: f1 <- function() { load("mydata.Rdata") # compute with objects from mydata.Rdata. } I wish to load mydata.Rdata only within the function f1. Perhaps I have misunderstood

Somehow I have lost the correct file association for .RData files. They are now associated with a text file editor. When I right click on any .RData file and try to change the association, R is not listed as a choice of program. I browse to c:\Program Files\R\rw2001\bin\Rgui.exe and select that file to open .RData, but Windows does not then place Rgui.exe in the list of programs to use. I can

Dear All, I suspect this is kind of dumb, but when I was under the thrall of the dark lord (read, using a W2K box), all my work in R files came out as foo.RData. I moved on to GNU/Linux, and all the old .RData files keep on working as they used. No problems in loading and stuff. But I use R from the terminal. Assuming I decide to switch to emacs, do I need to save my work as foo.r? what about my

Hi, I noticed a Rdata size issue that's puzzling to me. Attached find 2 example datasets in text file. Both are 100x5, so the sizes for both text file are the same. However, when I read them into R, the sizes are much different: tt<-as.matrix(read.table("tt.txt",header=T,row.names=1)) save(tt,file='tt.RData')

I got two .RData file e.g data.2005.RData & data.2006.RData I would like to combine these two different data set and make single RData file. in both file there are some NULL files are also available and I would like to clear this NULL files also. $ : NULL $ : NULL $ : num [1:43285, 1:8] -21.1 -21.1 -24.9 -24.9 -24.9 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : NULL ..

Hi, I have been using R under Windows but have started to use R (ver. 2.3.0,) under Linux (linux-gnu). I have been saving my workspace and I notice that I sometimes end up with 2 version of the .RData file: .RData and .Rdata. Can someone explain what is happening? I am not sure which one is loaded so I have ended up losing data by deleting the wrong file. I think the saved file should be

Somehow, I've managed to have my .Rdata files become `disassociated' from the R program. I am running Windows XP Pro. I have re-installed R 2.4 in an attempt to have it re-associate itself with .Rdata files, but to no avail. .Rdata files are now associated with a file compression program or alternatively with Rgui.exe. .Rdata files are represented by the blue R, but double-clicking on
