### Project raster without resampling
elevWGS84 <- project(elev, crs(chelsa))

### Project raster and resample to resolution of another raster
elevWGS84Resamp <- project(elev, chelsa)

res(elevWGS84Resamp)
res(chelsa)

### Project vector
riversWGS84 <- project(rivers, chelsa)
riversWGS84
cat(crs(rivers)) # using "cat()" to make it look nice
cat(crs(riversWGS84))
