plot.dendrogram and expressions
...ced to character before they are added to a plot with `text'. Is there
a specific reason to do so (expect for the determination of the size of
the character string to be plotted)? Otherwise one could plot the
attributes directly via
diff dendrogram.R /usr/src/R/src/library/stats/R/dendrogram.R

I agree.
A (very nice IMO) patch I'm currently testing is

`as.data.frame.matrix()` can produce a data frame without a `names` attribute
Hi all,
I recently learned that it is possible for `as.data.frame.matrix()` to
produce a data frame with 0 columns that is also entirely missing a
`names` attribute, and I think this is a bug:
```
# No `names`, weird!
attributes(as.data.frame(matrix(nrow = 0, ncol = 0)))
#> $class
#> [1] "data.frame"
#>
#> $row.names
#> integer(0)
# This is what I expected
