I've got this table:
A B

2 6.8 280
3 9.4 356
4 5.2 38
5 8.2 167
6 4.8 127
7 3.7 8
8 6.2 201
9 9.7 346
10 8.1 241
how can I get the variance and covariance of A and B?
?var
(If that hadn't been your first guess, you could always have tried:
??covariance
But maybe not:
RSiteSearch(covariance) # the term is ubiquitous in statistics
documents
... and I'm guessing that the number of choices offered would be a lot
smaller on someone's machine who is just starting out and has few
extra packages installed than it was on my machine. I think maybe you
need to do some more self-study of the "Introduction to R" document).
