I am trying to reproject a shapefile. For example, the land shapefile from Natural Earth.
library(sf) shape <- read_sf(".../ne_10m_land.shp") shape_proj<-spTransform(shape, CRS("+proj=gnom +lat_0=90 +lon_0=-50"))
I keep getting the following error, even when I try with CRSobj= or using other ways to express the CRS.
Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘spTransform’ for signature ‘"sf", "CRS"’
