Hi all,
Let Names a vector of chatacters. For example,
> Names
[1] "g 604 be-0 -p1 (602 matches)" "g 606 Phli-0 -p2 (517 matches)"
[3] "g 608 alu-0 (659 matches)"
I try to use gsub or grep functions for two problems :
1. First, I would like to delete all the characters between parentheses.
[1] "g 604 be-0 -p1" "g 606 be-0 -p2"
[3] "g 608 be-0 -p3"
2. And, I would like to extract the characters between parentheses
[1] "602 matches" "517 matches"
[3] "659 matches"
Any idea?
Best regards,
Olivier
