[R-sig-Geo] "g.list" in rgrass7 returns an integer and not a char. vector

[Mathieu Rajerison]

Hi List,

I try to get the list of rasters which are in my working environment but
the result of execGRASS("g.list") is an integer, not a character vector

Why is that ?

> execGRASS("g.list", type="raster", pattern="global*") %>% class()
global_glob_rad_day1
global_glob_rad_day2
global_glob_rad_day3
[1] "integer"

How to get a list of my rasters as a character ?

Thaks in advance for any guidance,

Mathieu
