Hi, sorry if it is a too stupid question, but how do I a string search
in R:
I have a dataframe A with A$test like:
test1
bcdtestblabla2.1bla
cdtestblablabla3.88blabla
and I want to search for string that start with 'dtest' and ends with
number and return the location of that substring and the number, so the
end result would be:
NA NA
3 2.1
2 3.88
I find grep can probably do this but I am new to the function so would
like a good example.
Thanks,
Richard
