Setting data download folder to a temporary folder
/tmp/Rtmpa7aG5O/working_dir/RtmpqLa4Qt. This means that any downloaded
map data need to be downloaded again when you restart R. To avoid this
problem, change the default path to a permanent folder on your
computer. Add following lines to your .Rprofile file: {.ggOceanMapsenv
<- new.env(); .ggOceanMapsenv$datapath <- 'YourCustomPath'}. You can
use usethis::edit_r_profile() to edit the file. paste(R.home(),
'library', 'ggOceanMapsLargeData', sep = '/') would make the folder in
your R package location. Might require administrative rights.
