Hi,
I want to add a sentinel 2 image subset to a leaflet map, but I cannot.
First, I try to apply this code and then I will do it with my image.
library(mapview) viewRGB(poppendorf, 4, 3, 2)
But I get this error:

Error in raster::projectRaster(x, raster::projectExtent(x, crs = sp::CRS(wmcrs)), :
argument "method" is missing, with no default

Can anybody help me?
Thanks,

MIKEL

@mikel89larioja this is fixed in the development branch of the package which you can install with

devtools::install_github("r-spatial/mapview@develop")

[mikel89larioja]

Thanks for your time @tim-salabim, I install the package again, but the error continues.

Can you pls post your sessionInfo() after installation of the mapview develop branch

so you didn't install mapview from github. If you do, the problem should be solved.

[mikel89larioja]

I have tried to install it from GitHub, but I could not. Maybe It is due to I am not in my personal computer and I cannot install some things. I got this error:

You need to install package stars

devtools::install_github("r-spatial/stars")

[mikel89larioja]

Thanks @tim-salabim, after installing package stars the problem is solved.
