Hi Catherine,
If I recall correctly, the builders are headless (i.e. they don't
have displays attached), and Cytoscape does require a display to run.
Anything in my vignette that required Cytoscape I cached the images and
then inserted them into the vignette, I think I had a function that would
check if Cytoscape was available, and insert the static images if it wasn't
push_graph <- try(
{
# borrowed from createNetworkFromDataFrames
nodes <- data.frame(id=c("node 0","node 1","node 2","node 3"),
stringsAsFactors=FALSE)
edges <- data.frame(source=c("node 0","node 0","node 0","node 2"),
target=c("node 1","node 2","node 3","node 3"),
stringsAsFactors=FALSE)
RCy3::createNetworkFromDataFrames(nodes,edges)
}
)
if (inherits(push_graph, "try-error")) {
runCy <- FALSE
print("No connection to Cytoscape available, subsequent visualizations
were not run")
} else {
runCy <- TRUE
}
if "runCy" is FALSE from above code, the chunk will grab the previously
generated image instead.
Your only bet for testing Cytoscape functionality I believe is what you can
do locally, either on your direct machine or via a virtual machine.
Hope that helps,
-Robert
