phr_reaction_temperature: Specify a reaction temperature, pressure gradient

In paleolimbot/tidyphreeqc: Tidy geochemical modeling using PHREEQC

Description

Specify a reaction temperature, pressure gradient

Usage

phr_reaction_temperature(.number = 1, low = 0, high = 100,
  steps = 10, values = NULL)

phr_reaction_pressure(.number = 1, low = 0.5, high = 1.5,
  steps = 10, values = NULL)

Arguments

.number	The number of the gradient
low	The low temperature, pressure (degrees C, atm)
high	The high temperature, pressure (degrees C, atm)
steps	The number of steps to use between low and high
values	Explicit values to use (takes precedence over low, high, steps)
