Hi,everyone.
I have a problem when using the grep.
for example:
a - c(aa,aba,abac)
b- c(ab,aba)
I want to match the whole word,so
grep(^aba$,a)
it returns 2
but when I used it a more useful way:
grep(^b[2]$,a),
it doesn't work at all, it can't find it, returning

How can I chang the
try
grep(paste(^,b[2],$,sep=),a)
your version will match b2:
grep(^b[2]$,c(b,b2,b3))
