[R] Problem with X11

[klerer at sxmail.de]

Dear Lorenzo, Dear R list,[a] to all recipients: sorry, this email is html-against my own believes and because of inevitable constraints so far.[b] to Lorenzo: "...and I have recently update my R environment" sounds as that would be a gift of heaven! How did you manage to update and how exactly went the process of updating the whole R environment, as you put it? I turn to you since I have not received an understandable answer to that question yet (see [d] below for sessionInfo() details).[c] to all R users: I use as OS a debian derivative (Kubuntu) long-term service version; this spring/ early summer as I was told, a new LTS would be released. Has a new/ revised R version in release in 2016 any Achille's heel that is already known? I perceive that some of the (package) update issues I experience might be due to OS compatibility (see [d] below for sessionInfo() details).[d]> sessionInfo()R version 3.0.2 (2013-09-25)Platform: x86_64-pc-linux-gnu (64-bit)locale: [1]

I have never had this problem before. I run debian testing on my box
and I have recently update my R environment.
Now, see what happens when I try the most trivial of all plots

> plot(seq(22))
Error in (function (display = "", width, height, pointsize, gamma, bg,
:
  X11 module cannot be loaded
  In addition: Warning message:
  In (function (display = "", width, height, pointsize, gamma, bg,  :
    unable to load shared object '/usr/lib/R/modules//R_X11.so':
      /usr/lib/x86_64-linux-gnu/libpng12.so.0: version `PNG12_0' not
      found (required by /usr/lib/R/modules//R_X11.so)

and this is my sessionInfo()
