BiocPkgTools 1.0.3
Bioconductor has a rich ecosystem of metadata around packages, usage, and build status. This package is a simple collection of functions to access that metadata from R in a tidy data format. The goal is to expose metadata for data mining and value-added functionality such as package searching, text mining, and analytics on packages.
Functionality includes access to :
The Bioconductor build reports are available online as HTML pages.
However, they are not very computable.
The biocBuildReport function does some heroic parsing of the HTML
to produce a tidy data.frame for further processing in R.

## # ... with 1 more variable: bioc_version <chr>Because developers may be interested in a quick view of their own
packages, there is a simple function, problemPage, to produce an HTML report of
the build status of packages matching a given author regex. The default is
to report only “problem” build statuses (ERROR, WARNING).
problemPage()When run in an interactive environment, the problemPage function
will open a browser window for user interaction. Note that if you want
to include all your package results, not just the broken ones, simply
specify includeOK = TRUE.
Bioconductor supplies download stats for all packages. The biocDownloadStats
function grabs all available download stats for all packages in all
Experiment Data, Annotation Data, and Software packages. The results
are returned as a tidy data.frame for further analysis.

The R DESCRIPTION file contains a plethora of information regarding package
authors, dependencies, versions, etc. In a repository such as Bioconductor, these
details are available in bulk for all inclucded packages. The biocPkgList returns
a data.frame with a row for each package. Tons of information are avaiable, as
evidenced by the column names of the results.

package or set of packages that perform required tasks or are tailored
to a specific operation or data type. The bioc_explorer() function
implements an interactive bubble visualization with filtering based on
biocViews terms. Bubbles are sized based on download statistics. Tooltip
and detail-on-click capabilities are included. To start a local session:
biocExplore()The Bioconductor ecosystem is built around the concept of interoperability
and dependencies. These interdependencies are available as part of the
biocPkgList() output. The BiocPkgTools provides some convenience
functions to convert package dependencies to R graphs. A modular approach leads
to the following workflow.
data.frame of dependencies using buildPkgDependencyDataFrame.igraph object from the dependency data frame using buildPkgDependencyIgraphigraph functionality to perform arbitrary network operations.
Convenience functions, inducedSubgraphByPkgs and subgraphByDegree are available.A dependency graph for all of Bioconductor is a starting place.

The visNetwork package is a nice interactive visualization tool that implements graph plotting in a browser. It can be integrated into shiny applications. Interactive graphs can also be included in Rmarkdown documents (see vignette)
igraph_network = buildPkgDependencyIgraph(buildPkgDependencyDataFrame())The full dependency graph is really not that informative to look at, though doing so is possible. A common use case is to visualize the graph of dependencies “centered” on a package of interest. In this case, I will focus on the GEOquery package.
igraph_geoquery_network = subgraphByDegree(igraph_network, "GEOquery")The subgraphByDegree() function returns all nodes and connections within
degree of the named package; the default degree is 1.
The visNework package can plot igraph objects directly, but more flexibility
is offered by first converting the graph to visNetwork form.
library(visNetwork)
data <- toVisNetworkData(igraph_geoquery_network)The next few code chunks highlight just a few examples of the visNetwork capabilities, starting with a basic plot.
visNetwork(nodes = data$nodes, edges = data$edges, height = "500px")For fun, we can watch the graph stabilize during drawing, best viewed interactively.
visNetwork(nodes = data$nodes, edges = data$edges, height = "500px") %>%
visPhysics(stabilization=FALSE)Add arrows and colors to better capture dependencies.
data$edges$color='lightblue'
data$edges[data$edges$edgetype=='Imports','color']= 'red'
data$edges[data$edges$edgetype=='Depends','color']= 'green'
visNetwork(nodes = data$nodes, edges = data$edges, height = "500px") %>%
visEdges(arrows='from') Add a legend.
ledges <- data.frame(color = c("green", "lightblue", "red"),
label = c("Depends", "Suggests", "Imports"), arrows =c("from", "from", "from"))
visNetwork(nodes = data$nodes, edges = data$edges, height = "500px") %>%
visEdges(arrows='from') %>%
visLegend(addEdges=ledges)[Work in progress]
The biocViews package is a small ontology of terms describing Bioconductor packages. This is a work-in-progress section, but here is a small example of plotting the biocViews graph.
