problem with generalized singular value decomposition using LAPACK
Hi All, I'm trying to run generalized singular value decomposition (GSVD) function from LAPACK library. Basically my problem is that I can not run it for large matrices, I get a memory error. I'm using R 2.5.1. I tried this on intel centos5 machines with 2 GB memory and 8 GB memory. I have unlimited max memory,cpu time and virtual memory. LAPACK is already compiled for R

symbol size on a plot
Hi, I would like to get from a plot the size of the symbols plotted. Imagine I have the following plot function : plot(1:2,1:2, pch=15, cex=4) I would like the get the values SIZE1 and SIZE2 so that if I plot the following rectangle : rect(1.5,1.5, 1.5+SIZE1, 1.5+SIZE2) then the size of this square is exactely the same as the one of the symbols that have been plotted. Thanks for any idea. --

How to get pixel position of a plot
Hi, I would like to plot a graph on the jpeg device for example and to write a table associated to this plot where I have the pixel coordonates of each plotted point so that I could include the jpeg image onto a html page and get all the information about each point when the mouse button is pressed. The indentify() can do it but on the window device... Thanks for any idea. Philippe --

how to insert a double quote with the paste function?
Hello, I would like to write in a variable the following string : Hello "World" If I do cat("Hello ","\"World\""), I have the good result on the screen but it can not be affected to a variable. If I do the same thing with paste paste("Hello ","\"World\"") it does not work since \" seems to be not recognized. So what

R 2.9.0 slower than R 2.8.1 for the data.frame function
Dear developers, I have noticed difference in computation time for the data.frame function between R2.9.0 and R2.8.1. The older release is more efficient: typically, R2.9.0 spends three more time in the data.frame function. Therefore, when many calls of this kind is done inside a function, the additional time spent with R2.9.0 may be several minutes. Looking at the profiling results (see file

Generalized Singular Value Decomposition (GSVD)
Dear R-users, I couldn't find a function or some help in R-project web about the Generalized Singular Value Decomposition. In MatLab there is a simple function for this algebric issue (gsvd). Is there anything like that in R? And, if not, could you help me to apply this method in R?

Generalized singular value decomposition
Hello, I would like to perform a generalized singular value decomposition with R. The only possibility I found is "GSVD" that is based on LAPACK/BLAS. Are there other possibilities too? If not, has anybody used LAPACK/BLAS under Windows XP? How can I install them? Following [1] did not help. I hope this is the right place for my question. Thank you very much! Oana Tomescu [1]

Add on argument in seq()
Regardless of the value of the other arguments, the first element in the output of seq() is _always_ `from`.

Add on argument in seq()
Millot, I think the problem with that is that what you propose isn't a sequence starting at from in any meaningful way, and thus does not satisfy the contract of the seq function.

Add on argument in seq()
Hi. I have a problem with the default behavior of seq(), which gives the argument "from" when the argument length.out = 1. This behavior is annoying when the number of value determine in length.out is not predictable. Would it be possible to add an argument that propose the median/mean, i.e. (from + to) / 2 when length.out = 1 ? Examples: > seq(from = 1, to = 11, length.out=1) #

Thick stripes in the barplot() function
Dear all, Sorry to bother you, but I didn't find the solution in the R-help archive. I would like to change the thickness of stripes inside the barplot. Is there any solution to do that when using the barplot() fuction and the density option ? Or is there any other function ? Thanks very much for your help. Best regards. Gael.
