Hello,

I tried to merge the two data frames which are having the same column name and the values set to NA. It showed me an error

> total<-merge(l,h,by="a")
Error: cannot allocate vector of size 3.8 Gb

Can anyone suggest how to rectify and merge those two data frames!!

How large are your two data frames and of what class are they (DataFrame, data.frame, data_frame)? A bit more of a workable example will help in answering the question. Also do sessionInfo() from within R so the relevant information about your system is known.

dims(l)
dims(h)
class(l)
class(h)
sessionInfo()

If you are on Windows, you can set memory limit with the function:

memory.limit(size = NA)
