Hello everybody!

I'm using Perl regular Expression for find pattern in my data set.

The pattern is: NaQxy, where a=E, F, G or H and xy != 29. I have tried this:

pattern <- "^N[E-H]Q[0-9]{2,2}"
index <- grep(pattern, X, perl=T)   #where X is my vector

But the problem is the xy should not be 29. How can I solve this problem.

Thanks!!!



Regards,

Katrine
