About

Maintained by Ruida Zhong4 releasesCRAN page ↗GitHub ↗

Calculating the monthly conventional and self-calibrating Palmer Drought Severity Index (PDSI and scPDSI) using the precipitation and potential evapotranspiration data. The function to calculate PDSI is based on the C++ source codes developed by Nathan Wells, Steve Goddard and Michael J. Hayes, University of Nebraska-Lincoln. Reference: Palmer W. (1965). Meteorological drought. U.s.department of Commerce Weather Bureau Research Paper, https://www.ncdc.noaa.gov/temp-and-precip/drought/docs/palmer.pdf; Wells N., Goddard S., Hayes M. J. (2004). A Self-Calibrating Palmer Drought Severity Index. Journal of Climate, 17(12):2335-2351, DOI:10.1175/1520-0442(2004)017%3C2335:ASPDSI%3E2.0.CO;2.

url <- "https://cran.r-project.org/src/contrib/Archive/scPDSI/scPDSI_0.1.3.tar.gz"

install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.1.3) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("Sibada/scPDSI")

Development version from Sibada/scPDSI. Installs pak first if it is not already available.
