Hello.

I am new to R, so my question/problem might be very basic, but I cannot
figure out how to solve it.
So, I would really appreciate your help.

I would like to rename a variable in a very large file (181GB) called
"2013.xdf" that is saved on my external hard drive.

I tried running the following code to rename variable # 2 in the file and
save this change, which produced some errors that I cannot resolve:

> temp.data <- rxGetVarInfo("E:/2013.xdf")
> temp.data[2] <- "transsactionnumber"
> rxSetVarInfo(2013fixed.data, outfile)
Error: unexpected symbol in "rxSetVarInfo(2013fixed.data"
> rxSetVarInfo(temp.data, outfile)
Error in is.data.frame(file) : object 'outfile' not found
> rxSetVarInfo(outfile)
Error in rxSetVarInfoXdf(varInfo, file = data) :
  object 'outfile' not found


Please help me figure out how to do it right.

Gratefully,
--
