Using inst/extdata with vignette during package checking R 2.14.0

Question

I have a package which contains a csv file which I put in inst/extdata per R-exts. This file is needed for the vignette. If I Sweave the vignette directly, all works well.

Answer 1

Have you tried using system.file instead of hardcoded relative paths?

EC1 <- dot2HPD(file = system.file("inst", "extdata", "E_coli", "ecoli.dot", package = "your_package+name"))
node.inst <- system.file("inst", "extdata", "E_coli", "NodeInst.csv", package = "your_package_name")
