Hi, apologies if this is too simple but I've been stuck on the following for
a while:

 

I have a vector of strings: filenames with a name before the extension and a
variety of possible extensions

 

I want to select only those files with:

 1) a ".tab" extension

AND 

2) the character sequence "lad" anywhere in the name of the file before the
extension.

 

Surely this won't take long to do, I thought. (But I was wrong.)

 

What's the regexp pattern to specify here?

 

Thanks,

 

Jon Minton
