Dear list,
I have a very short question,
Suggest a dataframe of four columns.
df - data.frame(w,x,y,z)
I want this ordered the following way:
first by :x, decreasing = FALSE
and
secondly by: z, decreasing =TRUE
How can this be done ?
Thanks
Gunther

PLEASE do read the posting guide
On the R wiki site there is a general-purpose function
(sort.data.frame) that allows you to do this:
sort(df, by=~ x-z)
See: http://wiki.r-project.org/rwiki/doku.php?id=tips:data-frames:sort
