The following works fine - > odbcConnect("demoteam", uid = "demo", pwd = "demo") This causes R to crash - > oracle.info <- list(channel = "demoteam", uid = "demo", pwd = "demo") > demo.db.connect <- function(ora.info = oracle.info) { + channel

Thanks in advance for any help I can get on this. I'm trying to change variable names between 2 systems - R and old SPSS, Oracle. I'm using the grep() and gsub() commands but I'm getting the following result - > test.dat <- c("a", "b.c", "d.e.f", "p_q,r") > test.dat [1] "a" "b.c" "d.e.f"

I thought I'd field this question in case someone has already done this, before proceeding with trying to develop a function on my own.

Depending on the platform I'm working on, Windows or Unix, i'd like to be able to switch between UNIX

This solution refers to a specific column number (here: column number 2) and not to the actual length of the run, doesn't it? That is, in this simple example the column number 2 actually corresponds to the length "2", but this must not be the case in general. For
