Create an hyetograph

Source: R/hyet_create.R

hyet_create uses precipitation and date values to create a tibble that represents the distribution of rainfall over time. Returns an error if:

  • prec and date values don't have the same length.

  • prec is not a numeric vector.

  • date is not a POSIXct (times) vector.

hyet_create(date, prec)

Arguments

date

a numeric vector of precipitation values
prec

a POSIXct vector with date values

Value

a tibble with the variables date and prec

Details

This function checks the validity of precipitation and date values and returns an error if:

  • These vectors don't have the same length,

  • precipitation is not numeric or

  • date is not POSIXct.

Examples


# create date and precipitation values
date <- seq(from = as.POSIXct(0, origin = "2018-01-01"),
                  length.out =  100,
                  by = "mins")
set.seed(1)
prec <-round(runif(100,0,10),1)

# create hyetograph
hyet <- hyet_create(date, prec)
