Problem with metaMDS and large input file #152

Description

@V-Z
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
R console does not produce any output, it just hangs.

When I force quit R window, I get:

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.

I use openSUSE Linux R binary and vegan is compiled locally.
