[RkWard-devel] R plot problems.

[Prasenjit Kapat]

Hi,

I have recently installed the 0.4.5 version. The GUI looks great. I was 
impressed by the graphics device window and the "Welcome"/help pages. 

1. There is a certain issue with the display of plots. Sometimes after a plot 
command (either from RConsole or Run + Selection from script editor) the "R 
Graphics: Device 2 (ACTIVE) - RKWard" titled window appears, but the display 
is all empty (gray - the default window color). Often, by doing Device + 
Duplicate, I get a new device window with the plot displayed properly. 
Sometimes even this does not help (even after multiple duplications). 

When everything works fine (ie I do see the plot at first attempt), the 
following messages are displayed in the "rkward - Konsole"

rkward: *** Embed 14680065 into 71378978. window=0
not really withdrawn, yet in loop #20
not really withdrawn, yet in loop #40

not really withdrawn, yet in loop #580
rkward: > before reparent: parent=0x136
rkward: > Loop 0: > reparent of 0xe00001 into 0x4412822 successful

And when nothing gets displayed, the following error appears in the konsole:

rkward: *** Embed 14680065 into 71379746. window=0
not really withdrawn, yet in loop #20
 ............
not really withdrawn, yet in loop #9980
rkward:  failure to withdraw window

Here, number of times the statement "not really withdrawn, yet in loop #xxxx" 
is printed varies. 

The way out is to dev.off() a few times in the RConsole and try plotting 
again. But I haven't been able to deterministically recreate the problem. I 
will let you guys know if I can find a way to do that.

2. Many times, closing the "R Graphics: Device" window (by clicking the x on 
top right corner) does not actually close the device. Consequently the next 
plot doesn't even come up. I have to manually dev.off() in the RConsole to 
get things right.

Does this have anything to do with translucency (I have disabled it, but still 
no good) or dri/glx being loaded through xorg.conf ? 

There are few things with respect to the Distribution plots through the menu 
options, that I felt was not quite right. I will reserve that to another 
mail.

Thanks, keep up the fantastic work.
