when plotting raster, legend = FALSE doesn't work

[gsapijaszko]

Hi Robert,

after upgrade I have realized that legend switch in plot isn't recognized:

devtools::install_version("terra", version = "1.6.3")
#> Downloading package from url: https://cloud.r-project.org/src/contrib/terra_1.6-3.tar.gz
#> Installing package into '/home/sapi/R/x86_64-pc-linux-gnu-library/4.1'
#> (as 'lib' is unspecified)
library(terra)
#> terra 1.6.3
utils::packageVersion("terra")
#> [1] '1.6.3'
r <- terra::rast(system.file("ex/elev.tif", package="terra"))
terra::plot(r, legend = FALSE)

After downgrading it to 1.5.xx, it works as expected:

devtools::install_version("terra", version = "1.5.34")
#> Downloading package from url: https://cloud.r-project.org/src/contrib/Archive/terra/terra_1.5-34.tar.gz
#> Installing package into '/home/sapi/R/x86_64-pc-linux-gnu-library/4.1'
#> (as 'lib' is unspecified)
library(terra)
#> terra 1.5.34
utils::packageVersion("terra")
#> [1] '1.5.34'
r <- terra::rast(system.file("ex/elev.tif", package="terra"))
terra::plot(r, legend = FALSE)

^{Created on 2022-07-30 by the reprex package (v2.0.1)}

I got the same result with 1.6.5 from github

Thank you very much for reporting this. It works again.
There is a work-around with the current version:

plot(r, 1, legend = FALSE)

I am using terra 1.7.18 and get the same error

plot(r, 1, legend = FALSE) works
plot(r, legend = FALSE) does not
