Hi Kristi,
The period is there for a reason. If you want to extract that column like this:
x<-data.frame(a=1:3,b=2:4,c=3:5)
> names(x)[3]<-"dif of AB"
> x
a b dif of AB
1 1 2 3
2 2 3 4
3 3 4 5
> x$dif of AB
Error: unexpected symbol in "x$dif of"
> x$'dif of AB'
[1] 3 4 5
you will have to quote the column name every time.
