I want to eliminate certain observations in a large dataframe (21000x100). I have written code which does this using a binary vector (0=delete obs, 1=keep), but it uses for loops, and so it's slow and in the extreme it causes R to hang for indefinite time periods. I'm looking for one of two things: 1. A document which discusses how to avoid for loops and situations in which it's

I have a question for our European readers: how common is it to use commas as decimal points in spread-sheet and statistics applications? Is it an inconvenience to require that all data use a period as decimal point? (i.e., 3.14159 rather than 3,14159). We're trying to make our program as foolproof as possible, and would prefer not to give users a chance to have commas as both decimal

Hi. I want to use R with very large files, a couple hundred megabytes, but R crashes every time that I try. Reading help files seems to indicate that R ought to manage its memory itself. I know I have enough memory since stata handles these files perfectly well. I have a mac running OS 10.3 and am running RAqua 1.8.1. Is there anything I can do to make it deal with these files successfully?

Windows (both XP and 98) seems to have a problem with our GUI, written using R's tcl/tk package. When we open another window, and then return to the GUI, the GUI has old pieces of text left from the previous windows and/or places which are cut off where a window had been. Also, when it computes something, the window will often decide to move itself over for no apparent reason, so it moves

Hi. I have an ibook G3/800 running 10.2.4, with Mac's X11. Up until a few days ago, R was working fine but recently it stopped working. The error I get is: dyld: /usr/local/lib/R/bin/R.bin version mismatch for library: /usr/lib/libncurses.5.dylib (compatibility version of user: 6.0.0 greater than library's version: 5.0.0) Trace/BPT trap which seems to imply that it wants a higher

The R documentation for some of the foreign package's functions says that the set of variable labels becomes attributes in the resulting data frame. Thus, e.g., 5="strongly agree", 4="agree", etc. I'm happy that the labels are being passed, but unfortunately, when R summarizes the data, it will list it only as categories, and doesn't deal with the

How does one put quotes within quotes, if it's possible? I've tried replacing one set of the quotes by single quotes. If it's not possible, is there any way to do the following? > cmd <- "read.dta" > opt <- "convert.factors=FALSE" > data.file <- " file="/full/path/name.dta" " > eval(call(cmd,data.file,opt)) Prior to

I hope someone here knows the answer to this since it will save me from delving deep into documentation. Based on 22 pairs of vectors, I have noticed that tetrachoric correlation coefficients in stata are almost uniformly higher than those in R, sometimes dramatically so (TCC=.61 in stata, .51 in R; .51 in stata, .39 in R). Stata's estimate is higher than R's in 20 out of 22

Sorry, my question is if exists a command tkexit in R, i need a command how exit of tcl for close an aplication. How to use him. Thank

You might look at "eval" and "parse".

Dear all, I get a strange error when I find polychoric correlations with the ML method, which I have been able to reproduce using randomly-generated data. What is wrong? I realize that the data that I generated randomly is a bit strange, but it is the only way that I duplicate the error message. > n<-100 > test.x<-rnorm(n, mean=0, sd=1) > test.c<-test.x + rnorm(n, mean=0,

Hi. Does anyone know whether the following error is a result of a bug or a feature? I can eliminate the error by making ML=F, but I would like to see the values of the cut-points and their variance. tmp.vec<-c(0, 0, 0 , 0 ,0 , 1, 0, 2, 0 , 0, 5 ,5 ,3 ,1, 0 , 1, 5, 10, 27, 20, 9, 0, 1, 1, 12, 29, 57, 34, 0, 0, 1, 2, 11, 31, 32) tmp.mat<-matrix(tmp.vec, nrow=7)

Hi I've been running Samba 2.x for years but decided to move up to 3.0.2. I've set up a new samba server with a workgroup NEWBIOSS and netbios name PARETO. Im having problems setting up my domain admins. I used 'net groupmap modify "Domain Admins" unixgroup=domadmin' my 'net groupmap list' shows : System Operators (S-1-5-32-549) -> -1 Replicators

Hi I had a few test shares  created and they were working fine. Users could read or write depending on the windows group that was defined on the share. I have since removed the test shares and created the file structure needed and setup the smb.conf file with the share names.  I have also setup the groups and assigned them to the respective directories.  Problem is the users can connect to

Hi I'm finding it takes ages to download a roaming profile from the server when I log into Win2k or XP. A 4Mb profiles typically takes about 2 minutes (and 2 minutes to write back when I log out). I did a test and copied the profile directory from the server to my PC. Running under Win98 takes 1-2 minutes. Under 2K/XP it takes nearly 5 minutes. However, a single file of 4Mb only takes about

Hi I have successfully joined my Sun NAS device to my Samba PDC (version 2.2.10, security=user, encrypt passwords=yes) However, when I try to map a drive to \\nas\home it wont accept my (correct) password and the NAS log says : NetrSamlogon[BIOSS\janet]: SAMBA_ACCESS_DENIED (Samba PDC) Have I missed something ? Do I have to set up a trust account or is it to do with encrypted passwords ? --

Hi, i have been running R 2.11 compiles with the goto blas libraries successfully for about a year. I am running Ubuntu 10.10 64 bit. However, recently I have been periodically getting a segfault when running R (and numpy -- also compiled against goto blas).

Hi, I am running Linux (64 bit) R, compiled under gnu compilers. I am looking to compile a Fortran program with the ifort (the intel compiler) and then be able to import that as a library into my version of R. I am using the flags FC=ifort and SHLIB_FCLD=ifort, however ifort does not seem to recognize the libR.so file. Does any one have experience with this/know of a a way to load an ifort

Hi, I am trying to use the merge command in the data.tables package. However, when I run the command I am not sure if it is running the merge command from the base package or the merge command from data.tables. When I run "methods(generic.function="merge")' it informs me that 'merge.data.table" is "non-visible". I am just trying to run the merge command on two
