Bug in raster::crop?
I tried that too, but I am still getting the error. Alzira Ramos writes:
Maybe, you need to add raster::extent(c(-160,10,30,60)) r <- raster(nrow=45, ncol=90) r[] <- 1:ncell(r) e <- raster::extent(-160, 10, 30, 60) rc <- crop(r, e) On 2 May 2018 at 10:58, Julian M. Burgos <julian.burgos at hafogvatn.is> wrote:
No, I am still getting the same error, either using extent(c(-160,10,30,60)) or extent(-160,10,30,60). I can crop polygons with no problem. The strange thing is that it was working fine until a couple of days ago. I am not sure what changed... Vijay Lulla writes:
Works for me too...with same versions of everything. Maybe you can try e <- extent(c(-160,10,30,60)) ? Apparently, ?`extent` states that it needs either a Raster, Extent, matrix, or vector of four numbers. I don't understand why extent(-160,10,30,60) worked for me though!

Works perfectly for me, with the same versions of everything:
r <- raster(nrow=45, ncol=90)
r[] <- 1:ncell(r)
e <- extent(-160, 10, 30, 60)
rc <- crop(r, e)

Hello everyone, I am getting this error when using the crop function in the raster package. Here is an example, sing the example in the help file:
r <- raster(nrow=45, ncol=90) r[] <- 1:ncell(r) e <- extent(-160, 10, 30, 60) rc <- crop(r, e)
Error in extent(extent) : insufficient number of elements (should be
4)
I am using R version 3.4.4., and raster 2.6-7.
