dimnames(heart.data$x)[[2]]
[1] "sbp" "tobacco" "ldl" "adiposity" "famhist" "typea"
[7] "obesity" "alcohol" "age"
Note that the printed variable names do not use the column names
of the matrix.
In contrast, in S-PLUS the names are used; the printout begins:
x.sbp x.tobacco x.ldl x.adiposity x.famhist x.typea x.obesity x.alcohol
The reason seems to be that format.AsIs is losing dimnames. That could be easily fixed -- unless I'm overlooking something?
Fixed in R-devel.
