[R-sig-Geo] Error creating GlobalSoilMap object (GSIF package)

[Tomislav Hengl]

Sorry for that bug. You need to get GSIF v0.4-2 or higher and then the 
SoilGrids objects will compile 
(http://gsif.r-forge.r-project.org/SoilGrids.html).

Looks like R-forge is still building the package 
(http://r-forge.r-project.org/R/?group_id=1125). I will try to put the 
new version on CRAN next week. In the meanwhile you should be able to 
install it by running:

install.packages("GSIF", repos=c("http://R-Forge.R-project.org"), type = 
"source")
