[R] Trouble reshaping some data

[Andrew C. Ward]

I would appreciate some advice on the following task. I have
some data that currently looks like this:
  t1 <- data.frame(id=c(1,1,2,2), 
aspect=c("A","B","A","B"), score=c(10,9,11,12))

I'd like it to look like this:
  id  A  B
   1 10  9
   2 11 12

reshape() looks like a good candidate for this job but I'm
not really sure about the roles of timevar and idvar for
this dataframe. I tried
  t2 <- reshape(t1, direction="wide", timevar=t1[,3],
                idvar=t1[,2])
which is obviously ignorant and wrong.

Thank you in advance for any comments.
