Thank you very much for your help. I wanted the aggregate option. I have one more question regarding plotting I am working on Generalized Extreme Value Distribution (GEV). I am am using daily, 3-day and 7 days aggregated precipitation values to find maximum annual precipitation. Then develop three return level plots (say up to 200 years) and I want to plot the three gplots with their threshold in the same graph.
rlplot <- function(GEV_MLE1 = gev, GEV_MLE2 = gev1,
GEV_MLE3 = gev2,
rperiods = NULL, do_ci = TRUE,
period = "years", unit = "in",
ylab = "Return Level",
y_seq = seq(0, 30, 5), ylim = NULL,
AMS_pts = TRUE, PDS_pts = TRUE,
colors = NULL, plottitle = "Return Level Plot")
But i only get the graph back ground. Can anyone help on this
