reports yields

Usage

reportYields(gdx, detail = FALSE, physical = TRUE, level = "regglo")

Arguments

gdx

GDX file

detail

if detail=FALSE, the subcategories of groups are not reported (e.g. "soybean" within "oilcrops")

physical

if true (default) physical area (croparea) used for yield calculation; if false harvested area used for yield calculation

level

aggregation level of returned data ("regglo" by default)

Value

yield as MAgPIE object (Mt DM/ha)
