Ooops sorry for html tags... Just forgot to edit the message
before sending it...
So back to my question:
Thx for the hint, but what would I have used if "b","c" and "d"
were values of a dataframe for instance?
X is for instance a dataframe:
>X
Mypatterns
1 pattern1
2 pattern2
3 pattern3
Y is another dataframe.
If I do:
grep(X$Mypatterns,Y) this will take into account only the first pattern...
I could use a loop but I vaguely remember an elegant trick that combined
grep and %in%.
Stéphane.
