...manner that will also return overlapping (i.e. non disjoint) regular expressions? For instance, when running gregexpr("AAA","AAAAAA"), I get two matches, one at position 1 and one at position 4. I'd like to receive 4 matches at positions 1, 2, 3 and 4. Thanks, Schraga Schwartz Department of Human Molecular Genetics and Biochemistry, Tel Aviv University Medical School, Tel Aviv 69978, Israel.

...ried using the by() function. However, this was extremely slow (it ran for more than two hours before I stopped it). Also, it used up all of 16 GB of memory on my machine. Is there any more efficient function, both in terms of time and memory, to do this sort of thing? Thank you very much, Schraga Schwartz

...d indeed I couldn't find any Bwidget and Tktable files; however, I don't know how to get them and haven't been able to find them on the web; moreover, I'm not sure how to set the path in R to recognize them.

...why the program is searching the "program files" directory; since R is installed in the C:\R-2.6. In addition, when I try to run the splice index menu, the program just gets stuck; and I eventually use ctrl+alt+del to stop R. Again, I'd be grateful for any help.

Hello, I'm looking for an efficient function for calculating partial correlations. I'm currently using the pcor.test () function, which is equivalent to the cor.test() function, and can receive only single vectors as input. I'm looking for something which is equivalent to the cor() function, and can receive matrixes as input (which should make the calculations much more efficient).
