Hi all,

Today I submitted a new package called "pcxn" in bioconductor and I got the
following Abnormal built result:

Warning in fun(libname, pkgname) :
  no display name and no $DISPLAY environment variable

Error: processing vignette 'usingPCxNdb.Rnw' failed with diagnostics:
 chunk 4 (label = pcxn.network)
Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") :
  [tcl] invalid command name "font".

The pcxn.network function uses igraph::tkplot to return a network, which
works every time on several local machines. After searching for a while it
seems that whenever this problem arises its because of the igraph package
installation. How can I deal with this? Thanks in advance.
