GRASS Function not working currently

[Jo-Schie]

Hi @goergen95 .

Me again.
Seems like currently the Grass functions are not working as expected.

devtools::install_github("mapme-initiative/mapme.forest")
 
library(sf)
library(mapme.forest)
library(raster)

## TEST DOWNLOAD
# read in polygons of interest
aoi = st_read(system.file("extdata", "aoi_polys.gpkg", package = "mapme.forest"))

# download GFW data for the area of interest
raster_files = downloadGFW(shape = aoi,
                            basename = "pkgTest",
                            dataset = "GFC-2020-v1.8",
                            outdir = "../../johannes/data/",
                            keepTmpFiles = T)
# in case the projection between aoi and the downloaded rasters is different,
treeCover = "../../johannes/data/pkgTest_treecover2000.tif"
lossYear = "../../johannes/data/pkgTest_lossyear.tif"
co2Layer = "../../johannes/data/pkgTest_co2_emission.tif"

test<-
  statsGRASS(grass = grass,
             addon_base = "../../johannes/mapme.protectedareas/data-raw/addons/",
             areas = aoi,
             tree_cover = treeCover,
             tree_loss = lossYear,
             tree_co2 = co2Layer,
             idcol =  "id",
             thresholdClump = 6,
             thresholdCover = 10,
             years = 2001:2020,
             saveRaster = F,
             .tmpdir="~/shared/datalake/tempdir/")

results in:

Warning in statsGRASS(grass = grass, addon_base = "../../johannes/mapme.protectedareas/data-raw/addons/",  :
  IMPORTANT WARNING: The use of the CO2 emission layer during analysis is currently discouraged.
           Several routines need to be adapted since the usage of a new data set by Harris et al (2021) (see https://www.nature.com/articles/s41558-020-00976-6)
           Check out https://github.com/mapme-initiative/mapme.forest/issues/7 to recieve information if the issue has been solved.

can you confirm?
