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

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. --

I am trying to use the function aggregate with the median function but I get the following error: Error in FUN(X[[1]], ...) : Argument "INDEX" When I replace median by mean, it works perfectly Can someone tell me where the problem comes from?

Hi, I need to computed the GSVD of two matrices. For doing so I used in my C code the lapack routine dggsvd. But when I source my file gsvd.R I have the following error: Error in eval.with.vis(expr, envir, enclos) : BLAS/LAPACK routine 'DGGSVD' gave error code -1 Is there a problem with the parameters passed through the gsvd.R script? Is there a problem within the C script?

Hello, I have a MANOVA model and I want to test the following hypothesis: LBM = 0 where B is the parameter estimates. Is there any function to do this in R? Cheers, Philippe -- Philippe Hup?

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

Dear all, I would like to make a large scatter plot created with R available as an interactive web graphic, in combination with additional text-annotations for each data point in the plot. The idea is to present the text-annotations in an HTML-table and inter-link the data points in the plot with their corresponding entries in the table, i.e. when clicking on a data point in the plot, the

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

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) #

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.
