Hi,

The external data for flowWorkspace vignettes cannot seem to be loaded. No error message generated, just a blank character string returned. The external data for flowCore loads correctly.

flowWorkspace example

> BiocManager::install('flowWorkspace')
> library(flowWorkspace)

> flowDataPath <- system.file("extdata", package = "flowWorkspaceData")
> gs <- load_gs(file.path(flowDataPath,"gs_manual"))
Error in normalizePath(path, mustWork = TRUE) : 
  path[1]="/Library/Frameworks/R.framework/Versions/3.6/Resources/library/flowWorkspace/extdata/gs_manual": No such file or directory

It's true: in the flowWorkspace directory /Library/Frameworks/R.framework/Resources/library/flowWorkspace/extdata there is no file called gs_manual, only empty_workspace_9.2.xml

Have tried restarting R session, re-installing flowWorkspace - no luck

flowCore comparison:

> browseVignettes('flowCore')
> file.name <- system.file("extdata","0877408774.B08", 
+                          package="flowCore")
> file.name

Based on this line

flowDataPath <- system.file("extdata", package = "flowWorkspaceData")

I'd guess that you would also need BiocManager::install("flowWorkspaceData")
