In Mathematica there is a neat feature, where you can change the head of a list from "list" to say "+" and obtain a sum of the list elements. I can't find a way to sum a list of vectors of same length or list of matrices of the same dimension and was curious if something like that exists in R. do.call("+",list) doesn't work because "+" accepts only

Hi all, It seems that getAttr doesn't return "names" attribute properly as in getAttrib(x, R_NamesSymbol)); If you look at section 4.7.4 in "Writing R Extensions", the second example of SEXP out(SEXP, SEXP) returns NULL for the names attribute of the outer product. This is true for R 1.7.0 on both Win2000 with mingw and Redhat 9.0 with gcc. Is there something I am

Hi, I am trying to figure how to use dlm with constant terms (possibly time-dependent) added to both equations y_t = c_t + F_t\theta_t + v_t \theta_t = d_t + G_t\theta_{t-1} + w_t, in the way that S-PLUS Finmetrics does? Is there any straightforward way to transform the above to the default setup? Thanks, Tsvetan -------------------------------------------------------- NOTICE: If received in

Dear Rexperts, after building R 2.4.0 from source in a temporary directory (*without* installation), and subsequently moving the whole source/build tree to another location, I have noticed that I had to change the variables R_SHARE_DIR, R_INCLUDE_DIR, and R_DOC_DIR in the wrapper-script /lib/R/bin/R as to reflect the current situation. However, when I try to run the HTML help via

R: Is there a reason why there isn't a Windows Binary version of RQuantlib on CRAN? Usually when there is no binary, I just source the source code, but this one appears to have various calls and methods and things like that so I'm hesitant to do so. I know there has been a big discussion on why Rmetrics doesn't have source for unix/linux, but that isn't on CRAN. Through
