[R-sig-Geo] raster::stack fails with "missing value where TRUE/FALSE needed"

[Hugo Costa]

Dear list,

is there any reason for raster::stack retrieve and error (see below) for
the raster provided in dropbox
<https://www.dropbox.com/s/tdfxezlieka1ofd/gsw.tif?dl=0>?
Thanks

# this may read the raster from dropbox directly, but is slow
# r<-raster("https://www.dropbox.com/s/tdfxezlieka1ofd/gsw.tif?dl=1")

# download raster from
https://www.dropbox.com/s/tdfxezlieka1ofd/gsw.tif?dl=0
r<-raster("path/to/downloaded/raster")
stack(r,r)

Error in if (common.len == 1L) unlist(x, recursive = FALSE) else if
> (common.len >  :
>   missing value where TRUE/FALSE needed
>

# reduce extent (no error)
r2<-crop(r, extent(r)/2)
stack(r2,r2)
