`zip_datafiles` throws error if data in different directory

[tavareshugo]

zip_datafiles() seems to throw an error when data are in a sub-directory. Here's an example:

# work from temporary directory
setwd(tempdir())

# create a sub-directory
dir.create("data")

# download example data in there
download.file("https://github.com/rqtl/qtl2data/raw/master/ArabMAGIC/arabmagic.zip", 
              "data/qtl2data.zip", "wget")

# unzip contents
unzip("data/qtl2data.zip", exdir = "data")

# create new zip_datafiles - error
qtl2::zip_datafiles("./data/arabmagic.json")

I think the problem is in lines 76-79 of function, which change working directory, but then line 99 uses zip_file that includes the full path. Not sure lines 76-79 are necessary at all?

I think the problem I had was preventing the zip file from containing the full depth of directories.

Hi, @tavareshugo, It should be working now; thanks for reporting the problem, and particularly for providing the example!
