grid 4.0 generates wrong results when adding two complex units by sum()
Hi,
In grid 4.0, adding two complex units by `sum()` seems to give wrong results.
In the following example, `u1 + u2` gives the correct result, but `sum(u1, u2)` also `sum(unit.c(u1, u2))` give the wrong results.
```
library(grid)
u1 = 0.4*sum(unit(1, "inch"), unit(1, "mm"))
u2 = 0.1*sum(unit(1, "inch"), unit(1, "mm"))
u1
# [1] 0.4*sum(1inches, 1mm)

tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
Hello everyone
I am not sure when this appeared
(sometime post R 3.5.0 and after I switched to Mac OS Catalina).
I do not think it happens on all platforms (e.g. seems to work on windows).
But it seems that
tkimage.create()
no longer works on a Mac for all png files.
(It does work for *some* old png files I have on disk but I have not been able to determine what is different about the

I don't know what has changed with Catalina
But I just tried my tk console from the shell command tkcon
And got the following error.

lines through points in lattice legend
Hi,
I'm struggling to find if there is a simple way to make the lines and points overlap in a legend for a lattice plot using auto.key. ?Here is a toy example of what doesn't work (for me) as the lines and points are adjacent rather than overlapping:
library(lattice)
d <- data.frame(x = 1:2, y = 1:4, f = factor(letters[1:2]))
xyplot(y ~ x, d, groups = f, type = "b",?

strange interaction between rasterImage and Grid graphics
Dear all,
This may be specific to Mac, I haven't had a chance to test another
platform. Consider this,
plot(1,1,t="n")
rasterImage(matrix(1),1,1,1,1)
library(grid)
grid.rect(gp=gpar(fill="grey"))
The grid.rect covers the full device window as expected. However, when
I resize the window ever so slightly (interactive device) the rectGrob
is suddenly clipped to the previous

grid.cap() requires more time?
Dear all,
I am puzzled by the following behavior of the new grid.cap() function,
which appears to run out of time when capturing the output of a
graphic. It works fine if I introduce a Sys.sleep(1) before executing
more code,
library(grid)
quartz()
grid.circle(gp=gpar(fill="black"))
gg <- grid.cap()
dev.new()
grid.raster(gg) ## completely blank

strptime() keeps emitting warnings after establishing a handler with tryCatch()
Dear list members,
I have come about a peculiar behavior in R (4.0.2) which I would
describe as a bug.
On macOS, where `strptime()` raises a warning for invalid timezone
identifiers, the following code will continue to raise the original
warning with every subsequent call to `strptime()`:
```
# attach a handler for warnings for this call only:
tryCatch(strptime('2020-10-31 18:30', format

gList and gTree methods of grid::grobX
Dear all,
In an attempt to draw fill patterns in grid graphics, I have
encountered a behavior of grobX that I cannot understand from the
documentation. Consider this,
library(grid)
## gTree
g1 <- gTree(children=gList(
rectGrob(0.5,0.5, width=unit(0.8,"npc"),
height=unit(2,"cm")),
circleGrob(r=0.3)), vp=viewport(0.5,0.5))

Query for semi-transparency support
In ?par there is the following line:
"Semi-transparent colors are available for use on devices that support them."
I'm looking for a way to query for that support on the current device.
I'm pretty sure that this functionality exists at some level as I
remember seeing warnings to this effect but my searches have come up
empty. Is anyone familiar with a direct path to this

Wayne,
that one is unrelated, but interesting - you can fix it with
sudo install_name_tool -change \
/usr/local/lib:/opt/X11/lib/libtk8.6.dylib \
/usr/local/lib/libtk8.6.dylib \

There is a bug in tcltk with IDs on the libraries which I have worked-around for R, but not for wish.

tomcat still sees jvm version 1.4.2 in Cent OS 5
i chose to install tomcat during the OS install as well as java....however, since I needed to use a different jvm, i used the method described in http://wiki.centos.org/HowTos/JavaOnCentOS for Sun jdk 1.5.0_13 and it worked fine as I can tell, as using the alternatives --config java command, i see both 1.4.2 and 1.5.0 versions and choosing the 1.5.0 version yields the right version when doing a
