netcdf_to_df: Read Station-based evd NetCDF File into a Data Frame

In loopevd: Loop Functions for Extreme Value Distributions

Read Station-based evd NetCDF File into a Data Frame

Description

This function reads a NetCDF file with EVD parameters (e.g. loc and scale) with a station dimension and converts it back into a data frame. The function assumes that the NetCDF file has a 'station' dimension with associated variables such as latitude, longitude, and other station-specific data.

Usage

netcdf_to_df(netcdf_file, exclude_cov = FALSE)

Arguments

netcdf_file	The path to the NetCDF file.
exclude_cov	Logical, if TRUE, variables starting with 'cov' will be excluded. Default is FALSE.

Value

A data frame containing the data from the NetCDF file.

Examples

tf = tempfile("test.nc")
# Ten records of 20 random data generated from the fgumbel EVD
am = lapply(1:10, function(x) evd::rgumbel(20))
tab = as.data.frame(t(sapply(am,function(x) evd_params(x,"fgumbel"))))
tab$lon = rnorm(10,sd=10) #station latitude
tab$lat = rnorm(10,sd=20) #station longitude
loopevd::df_to_netcdf(df = tab,output_file = tf)
tab2 = loopevd::netcdf_to_df(tf)
