[R-pkg-devel] nparACT package: "working directory was changed to...resetting"

[Blume Christine]

Hi Duncan,



Thanks a lot! Good to see that you had a similar idea, I did just that...in my example it looks like this, however, that does not help, i.e. that is the code that is associated with the warning…



data(sleepstudy)

wd <- getwd()

name <- "sleepstudy_example"

newdir <- paste(wd,name, sep="/")

if (dir.exists(newdir)){

setwd(newdir)

write.table(sleepstudy, file = "sleepstudy.txt", row.names=FALSE, col.names = FALSE)

r <- nparACT_flex_loop(newdir, SR = 4/60, minutes = 435)

} else {

dir.create(newdir)

setwd(newdir)

write.table(sleepstudy, file = "sleepstudy.txt", row.names=FALSE, col.names = FALSE)

r <- nparACT_flex_loop(newdir, SR = 4/60, minutes = 435)

}

setwd(wd)

}



Best,

Christine

Previously you were allowed to change directory in an example.  Now you're not.  This makes sense:  the user might not want to change the working directory.



To fix this, just save the old directory, and restore it at the end of your example.  For example,



   olddir <- setwd(tempdir())

   # Run the rest of the example code here

   setwd(olddir)
