Delete/insert rows in data matrix
Hello all,
I have the following problem. I want to insert blank rows in an data frame
so as to make it comparable with another data frame with more rows. How can
I insert these rows?
If this is not solvable, then, alternatively, is it easy to delete rows from
a data frame?
Thanks for helping,

how to count unique observations by variables
Dear R-helpers,
I have a data frame with 3 variables, each record is a unique combination of
the three variables. I would like to count the number of unique values of v3
in each v1, and save it as a new variable v4 in the same data frame.
e.g.
df1
[v1] [v2] [v3]
[1,] "a" "C" "1"
[2,] "b" "C" "2"
[3,] "c" "B"

R + Linux
Dear all;
I'm planning to install Linux on my computer to run R (I'm bored of
W..XP). However, I haven't used Linux before and I would appreciate,
if possible, suggestions/comments about what could be the best option
install, say Fedora, Ubuntu or OpenSuse which to my impression are the
most popular ones (at least on the R-help lists). The computer is a PC
desktop with 4GB RAM and
