So the real challenge we have with this is finding a windows 10 box to debug on.
I suspect what is happening is a library load error within the modules that aren't loading but have no way of verifying that.

Libraries so far that I found to fail are: reshape, reshape2, lattice, hexbin, testthat, Matrix These libraries are usable from R itself. At the same time other libraries installed the same way, and located at the same place load with no problem, eg: curl, foreach, MASS, knitr, yaml
I am running
Postgres 9.4 on Windows 10 R - 3.3.1 dir: C:\Program Files\R\R-3.3.1\library R_HOME from Select * From plr_environ() is C:\Program Files\R\R-3.3.1
I also tried this with Postgres 9.5 and got the same error. There is no similar problem on my production Debian machine. I don't even know where to begin investigating.
(I have sent this same message to the mailing list as well. I am sorry for double posting but I am uncertain now what forum should I be using for issues.)
Thanks for any help. Balázs

Unfortunately I am completely unfamiliar with debugging. Is there a log, dump or similar file that I could send or look at to untangle this?
Unfortunately no.
Could you try creating an R program which attempts to load the same libraries directly in R run from the command line ? Admittedly this is a hail mary.

the single line library('reshape2')
executes without error in RStudio or in the R command line
but fails within a plr function
Can you try this either with the R path "C:\R\R-3.3.1\library" (no spaces) on your Windows box, or alternatively using path "/Program Files/R/R-3.3.1/library" (with space in path) on a Debian system to see how it behaves? I can try the latter at some point but will not have time for a while...
I can try the former one. Will let you know about the results.
I uninstalled and reinstalled R into "C:\R\R-3.3.1\" and changed the R_HOME variable. SELECT * FROM plr_environ() returns now with the new R_HOME value. Unfortunately the error remains: in a plr function library('catR') returns OK, but library('reshape2') gives the same error as before.
All of the failing packages look like they import other packages, whereas the ones that do not fail are standalone -- is that correct? Since the imported packages are also in DLL files, please try putting the R library directory (location of all of these package DLLs) into your system PATH environment variable. If I remember correctly I have seen that needed before.
Thanks for the idea, I have now tried that, but unfortunately it did not help.
I now have the following directories in my system PATH variable: C:\R\R-3.3.1 C:\R\R-3.3.1\bin\x64; C:\R\R-3.3.1\library\reshape2\libs\x64; C:\R\R-3.3.1\library\reshape2\libs; C:\R\R-3.3.1\library\reshape2; C:\R\R-3.3.1\library\;
also tried adding: C:\R\R-3.3.1\library\reshape2\libs\i386;
I restarted the machine.
library(catR) succeeds, but library(reshape2) - still fails.
Please let me know if there is anything else I could try. Thx.
Yesterday I tried library('lattice') in a plr function on my own Win10 VM and it loaded perfectly, even though I do not have the DLL dirs in the PATH. So apparently that is not the issue.
Is there anything none standard with your install other than moving the installation directory? I assume you got the R via CRAN for example?
library('lattice') runs fine for me too could you try library('reshape') - that fails for me I don't think I have anything non-standard with my R installation
sorry for the long delay, but this works fine for me also so I am still at a loss as to what the problem could be:
CREATE OR REPLACE FUNCTION public.testplr() RETURNS text AS $BODY$library('reshape'); return ("ok")$BODY$ LANGUAGE plr;
if that works fine on your box than it must be something with the setup of mine sorry for the bother
