R devel - Mar 2002 - legend - bug with argument angle (PR#1404)

When legend() is used with the angle argument as follows, not only the
boxes beside the legend text, but also the whole legend box is filled
with shading lines.
I think this is not intended:

 plot(1:10)
 legend(8, 4, c("A", "B"), angle=c(10, 80), fill=NULL,
density=20)


I'd suggest as a fix (legend.R of R-1.5.0):

25c25
<     rect2 <- function(left, top, dx, dy, ...) {
---
>     rect2 <- function(left, top, dx, dy, angle, ...) {
133c133
<     rect2(left, top, dx = w, dy = h, col = bg)
---
>     rect2(left, top, dx = w, dy = h, col = bg, angle = NULL)
141c141
<     rect2(left=xt, top=yt+ybox/2, dx = xbox, dy = ybox, col = fill)
---
>     rect2(left=xt, top=yt+ybox/2, dx = xbox, dy = ybox, col = fill, angle =
angle)

Thank you, Uwe!
The fix looks very reasonable and should make it to R-devel
soon.
