Warning: [tapp] it is not sensible to a single value as index (use app instead)
class : SpatRaster
size : 87, 61, 1 (nrow, ncol, nlyr)
resolution : 1, 1 (x, y)
extent : 0, 61, 0, 87 (xmin, xmax, ymin, ymax)
coord. ref. :
source(s) : memory
name : X1
min value : 193
max value : 395This is the expected result. There's no reason to use tapp if you know the vector of indices will always be constant, of course, but you can end up using a constant vector if it's computed from other code, and in this case the warning is just noise.
