cutting of raster image to selected extent?

Question

I have taken raster images from worldclim and I want to cut this raster image to Canada latitude and longitude (42,83, 53,141). I am new user in R so can anyone tell me how I cut this on R.

Answer 1

You can use crop() function from the package raster :

library(raster)
canada_cropped = crop(x = full_raster_image, y = your_extension)

Here x can be your raster image that you want to crop from, and y is the extent object (or an object you can extract from).

I would recommend using ?raster::crop where you can learn a lot more about this.
