Minimal code to generate "#> Error in x$.self$finalize() : attempt to apply non-function"
I think this is a minimal code sample to generate this currently mysterious (https://github.com/rspatial/terra/issues/165#issuecomment-811446604) error:
Error in x$.self$finalize() : attempt to apply non-function
I'm able to generate this message on macOS, Windows and Linux:

I tried to reproduce it on Windows 8.1 (8 GB) and Linux (64 GB) but it works fine for me. From my observations, this error is very random and executing the same code doesn't always return this error.
Probably the posted code can be simplified to the following form to not download 60 dependent packages:
library("terra")
download.file("https://github.com/Nowosad/spDataLarge/raw/master/data/nz_elev.rda",
"nz_elev.rda", mode = "wb")
load("nz_elev.rda")
nz_elev = rast(nz_elev)
plot(nz_elev)
#> Error in x$.self$finalize() : attempt to apply non-function
#> Error in x$.self$finalize() : attempt to apply non-function
#> Error in x$.self$finalize() : attempt to apply non-function
#> Error in (function (x) : attempt to apply non-function
#> Error in (function (x) : attempt to apply non-function
#> Error in x$.self$finalize() : attempt to apply non-function
#> Error in (function (x) : attempt to apply non-function
Edit: Reproduced after PC reboot.
I get the messages the first time I run this, in a new R session (no need to reboot the computer, for me). Here with a further refined approach.
library("terra")
library("raster")
#terra version 1.2.13
fnz <- "nz_elev.rda"
if (!file.exists(fnz)) {
download.file("https://github.com/Nowosad/spDataLarge/raw/master/data/nz_elev.rda", fnz, mode = "wb")
}
load("nz_elev.rda")
nz <- rast(nz_elev)
plot(nz)
#Error in (function (x) : attempt to apply non-function
#Error in x$.self$finalize() : attempt to apply non-function
#Error in x$.self$finalize() : attempt to apply non-function
#Error in x$.self$finalize() : attempt to apply non-function
#Error in (function (x) : attempt to apply non-function
It may be worth sending out the minimal example to the Rcpp developers listserv. Perhaps someone on there may be able to provide some insight into why this occurs.
It appears that this case has now been fixed; and hopefully most, if not all, other cases as well. Please open a new issue if you find another case of these messages with terra >= 1.6-20
