    Gnome mapping in wet lab environments

    I assume genomes were mapped, not gnomes...

    Is that how you spell it? I've no idea about chemistry but love some of the R packages their community are developing!

    Hi there,

    In your opinion what would be the advantage of this R approach compared to, say, direct graph visualization with GraphViz dot command, example:
    digraph STG
    {
       "Kirk" -> "Scotty"
       "Scotty" -> "Spock"
       "Spock" -> "Kirk"
    }

    I think the advantage is in situations where nodes have multiple edges. In the article there is a CTE that generates a network hierarchy, each node has three edges to other nodes. I suspect GraphViz can manage this too but many applications and packages can’t.

    Had some trouble getting this to work in RStudio, wouldn't install the packages as in the commented section. This worked though: 

    source("https://bioconductor.org/biocLite.R")
    biocLite()
    biocLite("graph")
    #biocLite("graphNEL") <- didn't work, fails but apparently wasn't needed, code runs w/out it
    biocLite("Rgraphviz")

    Nice post, thanks for the tips on graph viz tools.

    Thanks for the feedback, I’ll update the comments section in the next release with this.
