Thanks for your great help.
I'm now running your first suggestion on a 600.000 row sample after
verifying it works on a smaller sample.
It's now been running for 40 minutes.
Which method do you think will be faster?
Regards Derk

Hi Arun,
The second method is indeed working much faster. It worked fast for my
600.000 row record.
Still I have 2 bigger files where processing becomes an issue even though I
have lots of memory (32 gig) for the second statement:
res2-reshape(dat2,idvar=newCol,varying=list(2:26),direction=long)
Hi experts,
I have a dataframe with 100k+ records. it has a key/id column and 25 code
columns. I would like to restructure it having a row for each code column.
I have a structure like this (used dput):
structure(list(DSYSRTKY = structure(c(1L, 2L, 3L, 3L, 4L, 4L), .Names =
c(1,
2, 3, 4, 5, 6),

According to your first post,
NewDataFrame - data.frame(ID=integer(), DSYSRTKY=integer(), CODE=character
9 matches
