The code was developed by eBird and can be found here.
When I run the second set of code, this warning is produced and one cannot continue:
Warning message:
In unzip(tmp_bcr, exdir = tmp_dir) : error 1 in extracting from zip file
Here is the code that produces the error:
# download bcrs
tmp_dir <- normalizePath(tempdir())
tmp_bcr <- file.path(tmp_dir, "bcr.zip")
paste0("https://www.birdscanada.org/research/gislab/download/",
"bcr_terrestrial_shape.zip") %>%
download.file(destfile = tmp_bcr)
unzip(tmp_bcr, exdir = tmp_dir)
Could the slashes below be the issue when we look at the defined path on my PC?
> tmp_bcr
[1] "C:...\\AppData\\Local\\Temp\\Rtmpm8LNRB/bcr.zip"
Setting list = TRUE I am getting a data.frame with the file names, their length and creation date.
And no errors extracting the files.
tmp_dir <- normalizePath(tempdir())
tmp_bcr <- "~/Temp/bcr_terrestrial_shape.zip"
unzip(tmp_bcr, list = TRUE)
