Using 1.9.0 on WinXP...
I have a data frame, one column of which is named "rate". The column has
text entries like "fast", "medium", "slow", "very slow", and so forth. I
have not tried to make them factors, but maybe R did this automatically.
Anyway, I would like to display on the console rows that meet a rate
So I want to type something like:
and get back this sort of output:
test subject trial rate score
34 B27 3 slow 27
55 B55 4 slow 34
where test, subject, trial, rate, and score are all the
How do I do that??
