Sorry, I misread. I thought you want to get the columns inverted. It works
for rows analogously:

x=c(rep(1:10,4))
dim(x)=c(10,4)
x=data.frame(x)

x2=x[order(-1:-10),]
x2

Betreff: [R] Inverting data frame...row wise

Hi,

I have the data.frame with 4 columns. I simply want to invert dataset so
that last row becomes first...

I tried with rev(my_data-frame) but I got my columns inverted... not my rows


Thanks
