A fitting function
See PhenoTrs from package greenbrown for details.
PhenoTrs(x, approach = c("White", "Trs"), trs = 0.5, min.mean = 0.1,
formula = NULL, uncert = FALSE, params = NULL, breaks, ...)x |
seasonal cycle of one year |
approach |
approach to be used to calculate phenology metrics. 'White' (White et al. 1997) or 'Trs' for simple threshold. |
trs |
threshold to be used for approach "Trs" |
min.mean |
minimum mean annual value in order to calculate phenology metrics. Use this threshold to suppress the calculation of metrics in grid cells with low average values |
