Here is another way
require(stringr)
aaa<-paste0("a", 1:20)
bbb<-paste0("b", 101:120)
ab<-paste0(aaa,bbb)
ab
ptrn<-"([ab][[:digit:]]*)"
unlist(str_extract_all(ab, ptrn))
Hi,
I have a vector of strings like:
c("a1b1","a2b2","a1b2") which I want to spilt into two parts like:
c("a1","a2","a2") and c("b1","b2,"b2"). So there is
always a first part with a+number and a second part with b+number.
Unfortunately there is no separator I could use to directly split
the vectors.. Any idea how to handle such cases?
/Johannes
