get_t_graphs: Get temperature response graphs

In plantecowrap: Enhancing Capabilities of 'plantecophys'

Description

Get temperature response graphs

Usage

get_t_graphs(data)

Arguments

data	List of data output from fit_topt_VJs

Value

get_t_graphs returns temperature response graphs for Vcmax and Jmax from the group fitting process. Output is a list of graphs.

Examples

#Read in data
data <- read.csv(system.file("extdata", "example_2.csv",
package = "plantecowrap"), stringsAsFactors = FALSE)
#Fit ACi Curves then fit temperature responses

#You can get a graph using: graph[1]
