Dear all, I have written a little R program to convert images. See below. Within the loop over j (the filenames) memory consumption grows constantly. rm( ... ) inside the loop did not help. Memory does not grow if I remove the writeBin statements between the two #-------- marks. But obviously this is not solution I want... Thanks for any advice. Manfred Baumstark P.S. As I'm new to R:

Hello, I?m looking for examples on how to manipulate the ... internally, e.g. in a .Call or .External function. I?m particularly interested in accessing the environment in which each contribution to ... can be evaluated. So far, I?m using tricks involving passing down the sys.calls() and sys.frames() down to the C function. The documentation in

Dear list, I am writing C code to interface with R, and I would like to know the level of mutability for the type of a SEXP. I see that there is a macro/function TYPEOF(), and that it can be used as an l-value, as well as a macro/function SET_TYPEOF(). My question is "should the type be considered immutable, or it can it change after the SEXP has been created and used for a while ?".

Using the IRanges package from Bioconductor and somewhat recent R-2.9.1. ov = IRanges(1:3, 4:6) length(ov) # 3 seq(along = ov) # 1 2 3 as wanted seq_along(ov) # 1! I had expected that the last line would yield 1:3. My guess is that somehow seq_along don't utilize that ov is an S4 class with a length method. The last line of the *Details* section of ?seq has a typeo. Currently it is

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.
