r - Using gsub instead of strsplit or scan -


are there other possibilities split string instead of?

unlist(strsplit("1.2.3", "[.]")) scan(text="1.2.3", what="", sep=".")

out of r's pattern matching functions base package (see ?gsub), gregexpr right 1 use here. identify start , end positions of chunks of characters not ., can reconstruct them using regmatches:

x <- "1.2.3.4as.zz2.zzxd3"  regmatches(x, gregexpr("[^.]+", x))[[1]] # [1] "1"     "2"     "3"     "4as"   "zz2"   "zzxd3"

but really, don't see gain on using strsplit. if tell not it, maybe of more help.
