Problem installing Rgraphviz in R

Question

[biomagician]

Hi,

I am having trouble installing Rgraphviz in R. Any kind soul to help me?

   /private/var/folders/z2/rt6qxntd3tg5bjmqlqnm0mdm0000gn/T/RtmpXu5l21/R.INSTALL1127235532a82/Rgraphviz/src/libunix/lib/graphviz

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
     during execution

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

  Rgraphviz is unable to be loaded.  This typically is a symptom of an
  installation problem.  From 2.x.x onwards, Graphviz ought to come bundled with
  Rgraphviz.

Could you post the output of sessionInfo()?

Interesting...

usually gives a list of installed packages. I wonder what these DLLs are...? dynamic-linked library?

[h.mon]

The key here is maximal number of DLLs reached, which you got both when trying library(Rgraphviz) and sessionInfo(). R has a hard limit on the number of shared libraries which can be loaded (apparently 100, see here and here). Close your session and try again. Are you loading a lot of packages at start-up?

[cpad0112]

Not a hard limit. Number of max number of DLLs can be increased by tweaking .Renviron. Default seems to be 100 as you mentioned.

[biomagician]

Hi,

Thanks, I have increased the maximum number of DLLs in .Renviron and it works now. Do you know what these DLLs are?

C.

[biomagician]

Hi,

I am using loads of packages even though I am not 'loading' them with the 'library()' function. I use the functions inside the packages with the syntax packageName::functionName.

[biomagician]

What is a 'library'? and what is a 'shared library'?

C.

[h.mon]

library() is a R command to load packages.

A shared library (or dynamic-link library in windows) are, well, libraries of functions that can be used (shared) by many executables.
