I created a weekly precipitation data, trying to tackle issue #45
Not sure I did it right. Data comes from CHIRPS V2.0 and is aggregated to weekly using a 53 week year (
lubridate::week()). From what I recall, it was not possible to use time series with fractional frequencies inSPI().Here is an exemple on how to use the dataset
#' data(campinas)
#' campinas_ts <- ts(campinas$prcp, frequency = 53, start = c(1981, 1))
#' spi(campinas_ts, scale = 12)
Cheers and thanks for your great work
