...and instead created registry entries pointing to the CD So the solution that worked for me is - copy RecourceKitCD:\source\gnu\perl\*.* and it's subdirectories to my HD (e.g. C:\NTRESKIT\perl), - change to this directory (e.g. C:\NTRESKIT\perl) - and run INSTALL.BAT (which updates the registry approbriately) Well, besides having some files twice in C:\NTRESKIT\perl and C:\NTRESKIT\perl\bin (e.g. perl.exe) (check your path) it works now.

...fine these functions in the base package. As example consider a class that shall behave like a matrix but will be copied by reference rather than by value (may be speed efficient, if a lot of functions manipulate the matrix). This can be done by wrapping the matrix in an environment and writing approbriate methods for dim, "[", etc. Here an example of some of its code # An example class that wraps a Matrix in an environment to allow pass by reference MatrixRef = function(mat) { m = new.env(parent=emptyenv()) assign("mat",mat,envir=m) class(m) = c("MatrixRef"...

...writing/reading data rowwise. I expect this to be rather slow. Is it possible to have this done in C instead of R? If in R, might it be that the sequence of multiple rbind() leads to memory segmentation (growing lists)?? May be one should ask on R-Help, if it is better to first create an object of approbriate size and then replacing single rows. (6.2) block read/write Reading all rows at a time with sqlgetresults() could run into memory trouble. Fetching single rows using odbcFetchRow() probably creates slow looping problems in R. I think the interface would become more suitable for big datasets if it...

Hi, i want to use R as a filter in a Unix-like way. So i want to start it with producerTool | R --no-save --no-restore --slave < Rscript | anotherConsumerUnixTool inside the Script i put the results to stdout, works fine, but how to read in from stdin? Its obvious that i have to source the Rscript in a different way. Any Hints? My second question is, if there is a possibility to use

I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it read.table()s data from a file with changing filename. As I understand no command line parameters are available for that, so instead I tried to pass the filename to an approbriate .RProfile, which works roughly, BUT ## this is my %R_USER%\.RProfile im <- read.table("d:/temp/im/temp.csv", header=TRUE, sep=",") nam <- names(im) nnam <- nchar(nam) newnam <- substr(nam, 2, nnam-1) # change names from e.g. <"x"> to <x> names(...
