My package RCyjs reads an html/js/css file when the constructor is called, then
sends that file to the user’s browser.
The actual path to that file is calculated at global scope in RCyjs-class.R:
cyjsBrowserFile <- system.file(package="RCyjs", "browserCode", "dist",
"rcyjs.html”)
That file cannot be found at runtime. Using
options(error=recover)
I can trap that error, finding these two different interpretations of
system.file(package=“RCyjs”):
cyjsBrowserFile:
"/Users/biocbuild/bbs-3.8-bioc/meat/RCyjs.buildbin-libdir/RCyjs/browserCode/dist/rcyjs.html”
system.file(package="RCyjs")
"/Library/Frameworks/R.framework/Versions/3.5/Resources/library/RCyjs”
It appears that cyjsBrowserFile is assigned at the build system’s package
construction time, not at the package load and use time.
Maybe this is new behavior? Any suggestions on how to defer the calculation
of system.file(package=“RCyjs”) till run time?
Thanks!
