similar to: managing .RData

I frequently use Makefiles to manage routine data manipulations and repeated analyses where the "raw" data tend to change with time. With S/Splus, this has worked quite naturally, as long as I'm careful to use S object names that map directly to Unix/Linux filenames. For example, say I'm building a particular graphic (chart.ps) from a data.frame in S (mydata) that comes from an

Hello R-users, is it possible to navigate from one workspace to the other from within an R session or does one has to close R and restart it from the directory where resides the desired workspace? For example from Splus I have this little function, see at the end, which I used all the time to navigate between valid Splus directories. I find this particularly usefull when I develop new

Dear R-users, I need to load outputs from multiple previous calculations into one R session for comparison and (cross-)analysis. The previous calculations are stored in different directories in .Rdata files (I don't know if this is the best storage for later usage, but the previous project could be recalculated and saved into different format, if needed, potentially.) I can load consequently

Hello! I have Windows 7 Enterprise and two versions of R installed: 2.15.3 and 3.0.0. Before I had R 3.0 I made it a setting that all .RData files - when I double-click on them - were opened by R 2.15.3. Now I want them to be opened by R 3.0 instead of R 2.15.3 (but I don't want to remove R 2.15.3. yet). I right-click on some .RData file, select "Open with" - "Choose default

It could be that the following may be due to something wrong that I managed to do (I cannot think what...) but I submit this report in case it is something that you want to know about (I have solved the problem by removing .Rprofile as I describe below). 1. After compiling/installing R 0.90 (an uneventful process), it worked perfectly the first time, and it read .RData written by the previous

I don't want to bother anyone with specific questions because I am a R newbie and I see that there is TON ( emphasis on Ton ) of documentation out there but could someone just tell me the best placed to look/read for learning about ( for R-2-2.1 in Windows ) .Rprofile .REnviron. .Rdata .First function ( analogous to the one in Splus ). Analog of Splus Chapter Basically, I want to

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, 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')

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]]

Hi, I have problem with the restore function in some .RData using R 1.9.0 Look the error: [ronaldo at zeus RAnalise]$ R ... Error: object 'family' not found whilst loading namespace 'MASS' Fatal error: unable to restore saved data in .RData But if I load this .RData with the load() function all objects are recovered. [ronaldo at zeus RAnalise]$ R --no-restore-data ... > ls()

Dear developers. Have spend just 1 h searching for a bug in a new version of a new version of a package. I was getting a segfault all the time. "Funny" thing - there was no error neither in the S nor in the C code. To solve the problem I had to delete the .Rdata file! What I observed. If the .Rdata file was generated while a previous release of a package was installed in the

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

Hi, I am trying to access many .Rdata objects and do some operations with them using a loop. I can load the files but can't access them. The files' names are stored in a character vector called "names". After loading the objects, I can view each one using ls() and see that two objects are present for each. I am trying to access the one with the name which is the same as the

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 ..

Hello, I've been migrating my computing to R and have not had any major problems running old Splus programs in R. However, the one thing I am missing is the ability to attach directories full of general utility functions from whereever I happen to fire up an R session. As a consequence, I find myself making many duplicate copies of these little general purpose functions by cutting and

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

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.
