plot_rec68: plot for hyperbolic tangent models models

In zhujiedong/lrc_start: light response curve fit start values For LI-6400 and LI-6800

Description

plots of different parameter values in one plot, to determin the range of start values, plot_rec64 for LI-6400 data, and plot_rec68 for LI-6800 data.

Usage

plot_rec68(df, Am = max(df$A) - min(df$A), Rd = min(df$A),
  alpha = 0.01)

Arguments

Am	is the gross photosynthetic rate
Rd	dark respiration rate
alpha	is quantum yield at low light intensity
x	is the PAR intensity of the leaf

Details

use ggplot2 geom_smooth to fit the calculate data, generally the fit method is loess, but it does not matter, as we just want to see these data overlap with the measured ones as much as possible.

Examples

## Not run: 
plot_rec64(lrc64, Am = 23)
plot_rec68(lrc68, Am = 15, alpha = 0.01)

## End(Not run)
