I would like to project the coordinates of the 2012 Peruvian census to work with another raster layer that has the following coordinates reference system :
"+proj=utm +zone=18 +south +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs ".
The answer of the post https://gis.stackexchange.com/questions/31743/projecting-sp-objects-in-r did not work in my case.
crs(census)
CRS arguments: +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0
newCRScensus=CRS("+proj=utm +zone=18 +south +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs ")
projcensus=spTransform(census,crs=newCRScensus)
Error in spTransform(census, crs = CRS("+proj=utm +zone=18 +south +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs ")) : second argument needs to be of class CRS
I don't understand the error message since the second argument is indeed of class CRS.
Any suggestions for another way of projecting the geographical coordinates is welcomed.
