[R] Bug or my misunderstanding?

[Bert Gunter]

Folks:

Before I waste someone's time with a stupid bug report, could I get
feedback as to whether the following really appears to be a (minor)
bug?

Summary: get_all_vars does not seem to handle multiple responses correctly.

Example:

> y <- matrix(runif(12),nc=3)
> x <- 1:4
> lmfit <-lm(y~x)

> model.frame(lmfit) ## OK
         y.1        y.2        y.3 x
1 0.02159809 0.15593110 0.59007262 1
2 0.91169201 0.30725236 0.41035328 2
3 0.45079051 0.29174545 0.18771042 3
4 0.07983415 0.37301448 0.70319143 4

> get_all_vars(lmfit)## not OK ?
           y         x        NA NA
1 0.02159809 0.1559311 0.5900726  1
2 0.91169201 0.3072524 0.4103533  2
3 0.45079051 0.2917455 0.1877104  3
4 0.07983415 0.3730145 0.7031914  4

## model.frame() gives correct response variable names; get_all_vars() does not.

R version 3.0.2 (2013-09-25)
Platform: i386-w64-mingw32/i386 (32-bit)

Many thanks.
