Question

So I have many data frames and I’m trying to merge them.
Some of them are in the form:

    sites1  AA1 SA
1   13: C   0.360828
2   14: S   0.017064
3   15: I   0.010810

Others are:

    sites2  AA2 Freq
1   1:  X   0.013
2   1:  S   0.987
3   2:  L   1.000

I have another data frame linking the proper data frame from the first set with the one from the second set and it goes like this:

    V1  V2
1   1JH6    AT4G18930
2   3MXZ    AT2G30410

with the name on the left side corresponding to one data frame and the name on the right side corresponding to another data frame.
I’m trying to merge them by doing

for (i in 1:n){
  name = paste("1",names2[i,2])
  assign(name,merge(names2[i,1],names2[i,2]))
}

but this just returns a data frame with the two names.. Any help?

Answer 1

try replacing the assign statement inside your for loop with the following

     assign(name,merge(get(as.character(names2[i,1])), 
                       get(as.character(names2[i,2]))))

---

Also, consider fixing the name = paste.... statement as follows:

   name = paste("T1",names2[i,2], sep="")
   # added sep="" to not have a space.
   # changed the name so that does not start with a number
