Package 'infiltrodiscR'

Cumulative infiltration and sqrt of time Using time and volume from field spreadsheets, the Cumulative infiltration and sqrt of time are calculated

Description

Cumulative infiltration and sqrt of time Using time and volume from field spreadsheets, the Cumulative infiltration and sqrt of time are calculated

Usage

infiltration(dataset, col_name)

Arguments

dataset	A tibble or data.frame including time and volume
col_name	vars including time and volume

Value

A tibble giving three new columns: sqrt_time, volume_infiltrated and infiltration

Examples

infiltration(data.frame(time = c(0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300,
0, 35, 65, 95, 125, 155, 185, 215, 245, 275, 305),
volume = c(95, 89, 86, 83, 80, 77, 74, 73, 71, 69, 67,
           83, 77, 64, 61, 58, 45, 42, 35, 29, 17, 15)))
