...ning digits in a special way: Do a normal string-compare up to the point where both string elemnts are numerical. Find then an outcome based on the number of consecutive digits in the strings while disregarding the value of the digits, eg a12b < a123. I guess then this order should hold: a12 == a22 < a1b, for these strings. Looking at StringRef::compare_numeric(StringRef RHS), the problem is, for a12 and a1b, Data[1]==RHS.Data[1], and the continue is reached. Data[2] is then less than RHS.Data[2], so a12 < a1b. But in the case for a22 and a1b, we get the opposite, since '2'!=&...

Is there an element-by-element multiplication in R, like the .* operator in Matlab? eg: A (2x3) B (2x3) C=A.*B C (2x3) C = [[a11*b11 a12*b12 a13*b13]; [a21*b21 a22*b22 a23*b23]] I can't find one... Thanks -Mike Gates

Dear all, suppose I have a vector with elements as: Vec <- c(2,3,4,5,6) Now I want to have all possible combination of length 3 using those elements and without any repetition. Like, I want to have 1 possibility like 2-3-4 but not 3-2-4. Can somebody guide me how to achieve that in R? Thanks for your help.

I believe we have a bug in compare_numeric() causing it to be non-transitive sometimes. It is supposed to provide a total ordering of strings.

Take this case for example (http://code.google.com/codejam/contest/dashboard?c=agdjb2RlamFtchALEghjb250ZXN0cxjRzBQM), the files are usually of the form: A(number of lines for group 1) a11 a12 a13 a21 a22 a23 ... B(number of lines for group 2) b11 b12 b13 b21 b22 b23 ... I guess SAS may work pretty well in this kind of situation with data step. But I don't know how to handle them using R. Any suggestions?
