Greetings,
I've been using R (on Linux i686) for some time now and have been able to
accomplish a great deal of work with it. My special regards
go to all who helped to develop it and turn it into an impressive statistical
package.
Keep up the good work.
A couple things involving NAs:
1.
> y _ data.frame(x1=1:10,x2=0)
> y
x1 x2
1 1 0
2 2 0
3 3 0
4 4 0
5 5 0
6 6 0
7 7 0
8 8 0
9 9 0
10 10 0> y _ data.frame(x1=1:10,x2="0")
Error: arguments imply differing number of rows: 10, 1> y _ data.frame(x1=1:10,x2=NA)
Error: arguments imply differing number of rows: 10, 1
Is this considered consistent behavior?
2.> mean(c(NA),na.rm=T)
[1] NaN
I'd prefer an NA instead of an NaN (which should be reserved for 1/0).
Cheers,
