Dear R users, my problem today deals with my ignorance on regular expressions. a matter I recently discovered. Consider the following foo <- c("V_7_101110_V", "V_7_101110_V", "V_9_101110_V", "V_9_101110_V", "V_9_s101110_V", "V_9_101110_V", "V_9_101110_V", "V_11_101110_V", "V_11_101110_V", "V_11_101110_V", "V_11_101110_V", "V_11_...

...ain a sequence of rvs X_1, X_2... such that X_i is a deterministic function of U_i. Let us further suppose that F^{-1} is difficult to calculate, so one does not simply do X_i = F^{-1}(U_i). Now, a possible alternative would be use U_i to set a random seed for a sequence of pseudo-random numbers, V_{i1}, V_{i2},... Then we can use this V_{ij} stream for every i to simulate F using the basic rejection method. (Here we further assume that there is some available pdf g we can simulate from such that f <= Mg for some const M). So we have a picture that looks like U_1 (random number seed for):...

I have specified in the SAS Proc Mixed procedure that the variance-covariance structure is to be compound symmetric. Therefore, the variance-covariance matrix is a block diagonal matrix of the form, V_1 0 0 0 V_2 0 0 0 V3 where each V_i represents a RefSeqID. Moreover, for each V_i the structure within the block is v_{11} v{12} v_{21} v{22} where v_{11} and v_{22} are different probeids nested within the refseqid, and so are correlated.

Hi, According to help(sub), the ^ should match the zero-length string at the beginning of a string: sub('^','var',1:3) # "1" "2" "3" sub('$','var',1:3) # "1var" "2var" "3var" # This generates what I expected from the first case: sub('^.','var',11:13) # "var1" "var2"

I have installed R 1.6 for Linux from source, but unfortunately, I didn't check if the Xwindow headers were available, so I have installed it without Xwindows capabilities. Thus, I want to uninstall it and install it again properly with the required features, but I don't know how to uninstall R when built from source. I would appreciate any help on this. Thanks very much in advance!

Dear all, First I apologize if my question is quite simple, but i'm very newbie with R. I have vectors of the form v = c(1,1,-1,-1,-1,1,1,1,1,-1,1) (longer than this one of course). The elements are only +1 or -1. I would like to calculate : - the frequencies of -1 occurences after 2 consecutives -1 - the frequencies of +1 occurences after 2 consecutives +1 It looks probably something like
