final <- merge(DF1,DF2)

The error i get is

Error: cannot allocate vector of size 2.1 Gb
In addition: Warning messages:
1: In merge.data.frame(as.data.frame(x), as.data.frame(y), ...) :
  Reached total allocation of 1535Mb: see help(memory.size)

    You have to have some column in common to merge on. From what you desribed, with the same number of rows it’s just…

    final <- cbind(df1, df2)
