Issue with cc_sea and seas_ref URL

I'm running clean_coordinates
on a set of data with default test settings and it seems to run the tests fine except for when testing sea coordinates. When it finishes the warning messages read:
> 1: In cc_sea(x, lon = lon, lat = lat, ref = seas_ref, scale = seas_scale, :
Gazetteer for land mass not found at
http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/physical/ne_50m_land.zip
> 2: In cc_sea(x, lon = lon, lat = lat, ref = seas_ref, scale = seas_scale, :
Skipping sea test
I went to the website and copied the download address (which only seems to differ by having "https" at the beginning) and tried the following:
clean_coordinates(x = data, lon = "Decimal_Long", lat = "Decimal_Lat", species = "Genus_species", seas_ref = "https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/physical/ne_50m_land.zip")
This time it stops with the error:
> Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘proj4string’ for signature ‘"character"’
If I try to run cc_sea
on its own it comes up with the same warnings if run with default settings, and the same error if run with the given ref =
.
I've looked around but I haven't found anything that can help with this error. Is there a way I can solve this issue and get it to run cc_sea
alongside the other tests?
Resolved by downloading a local version of the zip file and reading it into R with:
sea <- st_read("ne_50m_land")
sea <- as_Spatial(sea) #convert to SpatialPolygonsDataFrame
and then using this in seas_ref = sea
command as part of clean_coordinates()
.
