similar to: .Rdata file size

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')

surely this not hard, but i can't figure it out. i'd like to overlay the results of two ecdf's. e.g. xx<--ecdf(x) and yy<--ecdf(y). i'd like to plot xx and yy on the same graph. thanks...mj [[alternative HTML version deleted]]

Hi, I'd like to return the rows of sampled values of a vector. Can't figure out how to do it. For example: I start with [3, 1, 7, 4, 10] that have position [1,2,3,4,5]. I sample [10,1,4] and I want to return [5,2,4]. I'm sure there's a simple way to do that but haven't been able to figure it out or locate it. Thanks in advance...mj [[alternative HTML version

Hi all, Here is the situation: I have 2 nodes MDS1 , MDS2 (10.0.0.22 , 10.0.0.23) I wish to use as failover MGS, active/active MDT with zfs. I have a jbod shelf with 12 disks, seen by both nodes as das (the shelf has 2 sas ports, connected to a sas hba on each node), and I am using lustre 2.4 on centos 6.4 x64 I have created 3 zfs pools: 1. mgs: # zpool

Dear all, in a current project I have a pretty huge .Rdata. Thus I was working with R --vsize 100 --nsize 1000000. Today when I tried to restart R I get the following error message: Error: a read error occured Fatal error: unable to restore saved data (remove .RData or increase memory) I increased memory up to --vsize 180 and --nsize 2000000, but the error reoccurrs. Is there a way to know

This may be in the documentation. If so, I missed it. If a site has multiple Lustre file systems, the documentation implies that there only needs to be a single MGS for an entire site (regardless of the number of file systems). However, I also know it is fairly common to have a combined MGS/MDT. So here are the questions. 1. If we are going to have several Lustre file systems,

hi all, i'm trying to get elements in a matrix into a vector. i need a "streamlined" way to do it as the way i'm doing it is not very serviceable. an example is a 3x3 matrix like 0 0 3 2 0 0 0 4 0 to a vector like 3 2 4 thanks...mj [[alternative HTML version deleted]]

I have 11 possible predictor variables and use them to model quite a few target variables. In search for a consistent manner and possibly non-manual manner to identify the significant predictor vars out of the eleven I thought the option "select=T" might do. Example: (here only 4 pedictors) first is vanilla with "select=F" >

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

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

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]]

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 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()

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 ..

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

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.

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

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
