- **Comment**:

Hi!

Thanks for reporting (and sorry about the long silence).

> If applicable: When doing the same thing in an R session outside of RKWard, do you see the same problem?
> RStudio and R console do not produce any output, they just hang.

This does look like an issue in R or package "vegan", then. You may want to report it to the vegan mainainters. Bug tracker appears to be at https://github.com/vegandevs/vegan/issues . While the symptoms are a bit different in RKWard vs. R console (crash vs. hang), this does not indicate a problem in RKWard to me.

If I got you wrong on this, or you have any other particular reason to believe that this should be addressed in RKWard, rather than the package, please just reply. Otherwise, I'll close this report in a few weeks.

Regards
Thomas

** [bugs:#138] NEEDINFO: Rkward crashes when calculating NMDS**

**Status:** open
**Group:** CRASH

---Problem description---
I encountered the error message quoted below. Additionally, I saw the following symptoms:
###Please fill in (if applicable)###

What - in detail - did you do directly before you encountered this problem?

library(vegan)
metab.pos.root1.concat.mrbayes.nmds <- metaMDS(comm=metab.pos.root1.concat.mrbayes, distance="manhattan", k=2, trymax=10000, engine="monoMDS", autotransform=FALSE, noshare=FALSE, stepacross=FALSE, wascores=FALSE, expand=FALSE, plot=TRUE)
# metab.pos.root1.concat.mrbayes has over 14000 columns and 18 rows

When you try to repeat the above, does the problem occur again (no, sometimes, always)?
Always.

If applicable: When doing the same thing in an R session outside of RKWard, do you see the same problem?
RStudio and R console do not produce any output, they just hang.

Do you have any further information that might help us to track this problem down? In particular, if applicable, can you provide sample data and sample R code to reproduce this problem?
No

RKWard is available in many different packagings, and sometimes problems are specific to one method of installation. How did you install RKWard (which file(s) did you download)?
https://build.opensuse.org/package/show?project=devel%3Alanguages%3AR%3Areleased&package=rkward

---Error Message---
Message code: r_engine_has_died
Connection closed unexpectedly. Last error was: QLocalSocket: Remote closed
The R backend will be shut down immediately. This means, you can not use any more functions that rely on it. I.e. you can do hardly anything at all, not even save the workspace (but if you're lucky, R already did that). What you can do, however, is save any open command-files, the output, or copy data out of open data editors. Quit RKWard after that. Sorry!
