Creating a new raster based on an sf vector fails when PROJ >=6

[Nowosad]

Creating a new raster based on an sf vector fails when PROJ >=6. Below you can see two examples, one on a computer with PROJ5.2.0 and one with PROJ7.0.0. This issue is related to #78.

Proj < 6

library(spData)
library(raster)
#> Loading required package: sp
library(sf)
#> Linking to GEOS 3.7.1, GDAL 2.3.2, PROJ 5.2.0
world = read_sf(system.file("shapes/world.gpkg", package = "spData"))
world_raster = raster(world, resolution = 10)
world_raster
#> class      : RasterLayer 
#> dimensions : 17, 36, 612  (nrow, ncol, ncell)
#> resolution : 10, 10  (x, y)
#> extent     : -180, 180, -86.35487, 83.64513  (xmin, xmax, ymin, ymax)
#> crs        : +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0

Proj >= 6

library(spData)
library(raster)
#> Loading required package: sp
library(sf)
#> Linking to GEOS 3.8.0, GDAL 3.0.4, PROJ 7.0.0
world = read_sf(system.file("shapes/world.gpkg", package = "spData"))
world_raster = raster(world, resolution = 10)
#> Error in if (!is.na(projargs) && !nzchar(projargs)) projargs <- NA_character_ : 
#>   missing value where TRUE/FALSE needed

I do not see this with raster 3.1-5 (CRAN) or 3.1-6 (github) with PROJ 7

library(sf)
#Linking to GEOS 3.8.0, GDAL 3.0.4, PROJ 7.0.0
world = read_sf(system.file("shapes/world.gpkg", package = "spData"))
world_raster = raster(world, resolution = 10)
packageVersion("sf")
#[1] ‘0.9.2’

Does it also work for you?

Yes, it works now. Thank you
