Suppose I want to have a regexp match against a string, and return all
the matching substrings in a vector of strings.
regexp <- "[ab]+"
strlist <- c( "abc", "dbabddadd", "aaa" )
matches <- gregexpr(regexp,strlist)
With this input, I'd want to return list( list("ab"), list("ab", "a"),
li
Try this:
regexp <- "[ab]+"
strlist <- c( "abc", "dbabddadd", "aaa" )
library(gsubfn)
s <- strapply(strlist, regexp)
s
# compactly show 1st few in ea component
str(s)

I'm new to R and very excited about its possibilities. But I'm
struggling with some very simple things, probably because I haven't
found the correct documentation. Here's a simple example which
illustrates several of my problems.

3 matches
