There are conditional capture-classes in rexex in addition to the variable span {.,.} operators, but when I suggested using more general patterns, you turned them down, with a desire for the more incremental approach.
his pattern extracts a larger number of cases:
sub("(.*)([a-z]{0,3}[-]{0,1}[0-9]{2}[a-z]{1,2}[0-9]{2,4}[a-z]{0,1})(.*)", "\\2",
ripley.tv$producto,
ignore.case = T)
If I take out the leading space in the capture group then I get all cases extracted but it trims down the size of many of them. This with a trailing character class that has space or "\n" as an separator seems to be very successfull in one pass:
sub("(.*[ \n])([a-z]{0,3}[-]{0,1}[0-9]{0,2}[a-z]{1,2}[0-9]{2,4}[a-z]{0,1})(.*)", "\\2",
ripley.tv$producto,
ignore.case = T)
