I try to use resample in terra with a median method and I get the following message "Error: [resample] " . Other methods works fine :
library(terra)
x <- rast( xmin=0, xmax=200, ymin=0, ymax=200,crs="epsg:2948", resolution=20)
y <- rast( xmin=0, xmax=200, ymin=0, ymax=200,crs="epsg:2948", resolution=10)
values(x)<-runif(100)
resample(x,y,method="q1") # works fine
resample(x,y,method="med") # not working
You do not report the version of "terra" that you are using, nor the error message that you get, but with the current (CRAN) version of terra I get:
library(terra)
#terra 1.6.17
x <- rast(xmin=0, xmax=200, ymin=0, ymax=200,crs="epsg:2948", resolution=20)
y <- rast(xmin=0, xmax=200, ymin=0, ymax=200,crs="epsg:2948", resolution=10)
values(x) <- runif(100)
resample(x,y,method="med")
#class : SpatRaster
#dimensions : 20, 20, 1 (nrow, ncol, nlyr)
#resolution : 10, 10 (x, y)
#extent : 0, 200, 0, 200 (xmin, xmax, ymin, ymax)
#coord. ref. : NAD83(CSRS) / MTM zone 6 (EPSG:2948)
#source : memory
#name : lyr.1
#min value : 0.01575427
#max value : 0.99837255
So it seems that you are using an older version and that you should update the "terra" package with install.packages("terra")
