Examples

ecocrop('potato', 5:16, 15:26, runif(12)*100)
getCrop('Acacia brachystachya Benth.')
crop <- getCrop('Hot pepper')
ecocrop(crop, 5:16, 15:26, rainfed=FALSE)

# with spatial data
tmin = tavg = prec = brick(nrow=1, ncol=1)
tmin <- setValues(tmin, t(matrix(5:16)))
tavg <- tmin + 5
prec <- setValues(prec, t(matrix(15:26)))
crop <- getCrop('Hot pepper')
ecocrop(crop, tmin, tavg, prec, rainfed = FALSE)
