Hello, I would like to have a function that retrieve matching strings in the same way as with java.util.regex (java 1.4.2).
Example: f('^.*(xx?)\\.([0-9]*)$','abcxx.785') => c('xx','785') First of all: Is it possible to achiev this with grep(... perl=TRUE,value=TRUE )? As I would call this function very often with large data, I'm reluctant to use Sjava for performance reasons. Is this a wrong assumption that using Java directly would be slower or use more memory than to have a native R function? Does someone already has a solution for this :) Thanks, Marc Mamin ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
