Re: [R] R C API resize matrice

Hi, I don't think there is a native R API to do what you want here, but if the matrix is only used by you and not be exported to the other user, you can hack R data structure to achieve that goal. Because there is not too much context of your question, I will assume the whole point of resizing a

Please do not re-post -- you have asked this before here. As this list is about R programming help, it is perhaps not surprising that you did not receive a reply. You might try R-devel instead where " Questions likely to prompt discussion unintelligible to non-programmers or topics that are too te

[R] R C API resize matrice

Hi, Is there a way to resize a matrix defined as follows: SEXP a = PROTECT(allocMatrix(INTSXP, 10, 2)); int *pa = INTEGER(a) To row = 5 and col = 1 or do I have to allocate a second matrix "b" with pointer *pb and do a "for" loop to transfer the value of a to b? Thank you Best regards Morgan

Re: [R] Editing an R source code

Hi I do not use this package but this is written in manual: Custom splitting: All families except unsupervised are available for user defined custom splitting. Some basic C-programming skills are required. The harness for defining these rules is in splitCustom.c. In this file we give examples o

[R] Editing an R source code

I would love to use my own split-rule in the existing R package for random survival forests (randomForestSRC). Unfortunately, I have failed to locate the file where the splitting rules where coded in the source file. Is there anybody with an idea of how to find this specific file? Thank you! Dr Jus

Hi John, First, the unix and linux filesystem allows the use of any nonzero character in its filesystem filenames and the c functions open / fopen, symlink. rename, chdir and so on don't care about any tilde. If the open systemcall gets a file which begins with a tilde then it will try to open
