read.csv() returns a data.frame so the outer call to data.frame() is
superfluous.

Close:
You want
get(MyList)[1]
which gets the variable "MyList" -- else you are telling R to look for
something called "MyList[1]" which is a rare, but not actually
impossible object name.
As before, you really don't want to be using get() and assign() for
this sort of stuff though.
Please do try to do things the idiomatic way: it'll be easier in the
long run : I promise.
Cheers,
Michael
