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

[Blume Christine]

Actually, the report I received refers to the old 0.7 version…for whatever reason? The version I had submitted  was 0.8 in which I had corrected this. Well, let’s see…



Another issue seems to be that the text file the example is supposed to read in is not read (properly) using Debian:



Warning in is.na(data$activity) :

     is.na() applied to non-(list or vector) of type 'NULL'

    Error in 1:a : argument of length 0



I am reading in a text file with a numeric column (data$activity) and date or datetime (which is then converted using as.POSIXct. Subsequently, I check if there are NAs…



Any ideas what might be happening here?



Best,

Christine

I see:



$ wget https://cran.r-project.org/src/contrib/nparACT_0.7.tar.gz

$ tar xf nparACT_0.7.tar.gz

$ grep -r setwd nparACT

nparACT/man/nparACT_flex_loop.Rd:setwd(newdir)

nparACT/man/nparACT_base_loop.Rd:setwd(newdir)



so two examples don't restore the wd as Duncan was pointing out.
