Dear prof. Iacus,
I'm a newbie in R, and I'm interested in rgl package, because of my
work on social network analysis (I use sna package, but I would like to
use rgl to plot 3D graphs).
My problem is that I cannot find a way to load it, because the command
library(rgl) gives me this output:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
dlcompat: dyld: /Applications/R.app/Contents/MacOS/R can't open
library: /usr/local/lib/libpng12.0.dylib (No such file or directory,
errno = 2)
Error in library(rgl) : .First.lib failed for 'rgl'
Error in .C(symbol.C("rgl_quit"), success = FALSE, PACKAGE = "rgl") :
C function name not in DLL for package rgl
I try to change
in rgl's .First.lib function, but still get no results. I see that the
path it tries to follow doesn't match with the path that I use (which
is correct), but it's the only clue I can give you.
Can you help me?
thank you in advance,
ps: I'm having trouble also with the packages manager, which freeze R
while it tries to load the package (I think that it's in looking for
the documentation of the package but could not find it...)
