Dear friends,
I have a strange situation that shows up only on F32 (only linux distributions tried) but
does not show up on Windoze or Muck. The way to illustrate this is rather complicated, so
I will first summarize.
For my introductory students, I use a java-based front-end to R called Deducer. I am able
to install without a hitch and even bring it up and run some functions and graphical
displays. However, when I ask it to do a few specific functions, the windows all come
crashing down. So, my question is: how do I figure out the source of the problem? I have
used this program for years, and including last spring under F31, and linux has never been
an issue. This has been tried on three F32 machines by me and a former student and all
have resulted in crashes. Embarrasingly, these continue to work as expected with Windows
and MacOS, though installation, especially for the latter is a pain.
How can I get error messages out of this mishap to file a meaningful and targeted bug
report?
Any suggestions?

If you are interested, here is how I go about installing Deducer. I need R-core installed,
as well as curl-devel, and of course java. Other fedora packages may also be needed.
sudo dnf install R-devel curl-devel java-1.8.0-openjdk-devel
then:
sudo R
install.packages(c('JGR','Deducer'))
q()
Note that the second line will ask for which repo to use, and any are fine, the first one
is from
rstudio.com. Also, the installation function may ask for more libraries to be
installed.
Once installed, go to R and inside R, type:
library(JGR)
library(Deducer)
JGR()
The last function call will open a graphical interface with a jaguar logo (pretty cool).
All is well. In the bottom window type:
data(cars)
Then go to the graphical interface above, and under "Plots" ->
"Quick" -> "simple boxplot"
This opens a window, and put speed as x variable and run.
A window begins to open and the entire window system running JGR comes crashing down.
Btw, since I know the commands to give in R, on the commandline, when I call the function,
things work as expected. It is only on the JGR() window that it crashes.
The worst part? I get no error messages. So, how can I get error messages out of this
mishap to file a meaningful and targeted bug report?
Many thanks and best wishes,
Ranjan
