How about something like
my.data=my.data[,4:1]

This can be tackled in a similar way to the question by Mark Na which I
just answered. Using the same data frame construction we have
df <- data.frame(k1=1:2,k2=3:4,z=5:6,a=7:8,y=9:10)
df
k1 k2 z a y
1 1 3 5 7 9
2 2 4 6 8 10
revdf <- df[,rev(names(df))]
revdf
y a z k2 k1
1 9 7 5 3 1
2 10 8 6 4 2

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
