Yes! I'm guessing what he wants is
mutList$Alu[grepl("Alu",mutList$Alu)]
which can be simplified using with() to
with(mutList,Alu[grepl("Alu",Alu)])
But, in the absence of dput'ted data, we can't be sure. I would also
recommend that he reads up on list or data frame syntax, depending on what

You should use grepl() instead:
Alu<-mutList[grepl("Alu",mutList)]
or some variant of the above, depending on the actual structure of
mutList (which might be a data frame, but doesn't appear to be a
generic list). str() and dput() are both very useful for asking
well-formed questions.

Hi,
I have a list of mutations, called "mutList", of the form:
> head(mutList)
Alu
1 AluJ
2 AluJ/F(R)AM
3AluJ/FLAM
4AluJ/FRAM
5 AluJ/monomer
6AluJb
It contains about 500 elements and not all of them contain the
sequence "Alu". I tried using this code:
Alu<-
