[R-SIG-Mac] fcaR plot not working

[Simon Urbanek]

Peter,

hasseDiagram unfortunately depends on packages outside of CRAN, namely in Bioconductor, so you have to add the corresponding repositories before you install it, e.g.:

setRepositories(ind=1:4)
install.packages("hasseDiagram")
# also installing the dependencies ‘BiocGenerics’, ‘Rgraphviz’, 'graph’

Ideally, hasseDiagram would warn the user and provide an informative error, but that you’d have to take up with the author.

Cheers,
Simon
