bad variable names when printing a data frame containing a matrix (PR#10730)

library(glmpath) data(heart.data) # heart.data is a list, $y a vector, $x a matrix data <- data.frame(x=I(heart.data$x), y = heart.data$y)
data[1:2,]
x.1 x.2 x.3 x.4 x.5 x.6 x.7 x.8 x.9 y 1 160 12 5.73 23.11 1 49 25.3 97.2 52 1 2 144 0.01 4.41 28.61 0 55 28.87 2.06 63 1
dimnames(heart.data$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?
