b1" "0b" "b2" "40"
let1<-unique(unlist(strsplit(gsub("\\d+","",x1),"")))
split(unlist(strsplit(gsub("(\\w\\d+)(\\w\\d+)","\\1 \\2",x1)," ")),let1)
#$a
#[1] "a1" "a10" "a2"
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))

Dear Johannes,
May not be the best way, but this looks like what you described:

Unfortunately there is no separator I could use to directly split
