When building mypackage, everything seems to work:
library(devtools)
build(vignettes = T, manual = T)
* checking for file ‘/storage/Documents/client/validate/my
Not sure quite where RStudio puts it, but in a bare bones check operation the pdf version of the manual should be in a folder called mypackage.Rcheck If you created a mypackage-package.R file then when the package is installed, ?mypackage
should lead you to the html version of the manual. The vignette you can get by installing your package and doing vignette("mypackage")
.
