In addressing some problems reported with using the RefNet package last week, I promised to follow up with an account of the RefNet/PSICQUIC shiny app.  

For background: the Bioc RefNet package  modestly extends the PSICQUIC package ("Proteomics Standards Initiative Query Interface").  Together they offer annotated interactions from many sources; RefNet adds some hand-curated interaction datasets stored in the AnnotationHub.    With very few exceptions, each of the > 150 million searchable interactions includes 

1. Interaction type
2. Detection method
3. PubMed Id of article documenting the interaction
4. Many alternate identifiers, with protein identifiers dominating

An IDMapper class provides HUGO gene symbols for most of the several kinds of protein identifiers returned by PSICQUIC.   RefNet currently adds a human metabolic network (recon2), stamlab TFs, and a 2006 angiogenesis-related hypoxia signaling network; these are intended as examples of the variety of interactions supported.  More additions from the community will be eagerly received!

A gentle introduction to the PSCIQUIC/RefNet packages is provided by a  Shiny app included inRefNet, which you can try out as demonstrated below.  Note, however, that this app is new and may not yet be as robust as an established  web app.  Clickable links to gene descriptions and PubMed abstracts are provided for all the interactions returned from your search.

Copied and pasted from your post:

runApp(system.file(package="RefNet", "apps"), port=9999))

Error: unexpected ')' in "runApp(system.file(package="RefNet", "apps"), port=9999))"

Odd error. Try this

runApp(system.file(package="RefNet", "apps"), port=9999)

Error: could not find function "runApp"

shiny::runApp(system.file(package="RefNet", "apps"), port=9999)

Hi Mark,

Thanks for keeping at this.  

You have an out-of-date copy of RefNet.  You need version 1.2.0.  Please try this in your R session:

source("http://bioconductor.org/biocLite.R")
biocLite("RefNet")
suppressPackageStartupMessages(library(RefNet))
dir(system.file(package="RefNet", "apps")

You should see:

"server.R" "ui.R"     "www" 

And finally this then should work:

runApp(system.file(package="RefNet", "apps"), port=9999)
