plot.spwb_day: Plots simulation results for one day

Description

Functions to plot the sub-daily simulation results of spwb_day, growth_day or the transpiration calculations of transp_transpirationSperry or transp_transpirationSureau.

Usage

# S3 method for spwb_day
plot(
  x,
  type = "PlantTranspiration",
  bySpecies = FALSE,
  xlim = NULL,
  ylim = NULL,
  xlab = NULL,
  ylab = NULL,
  ...
)
# S3 method for growth_day
plot(
  x,
  type = "PlantTranspiration",
  bySpecies = FALSE,
  xlim = NULL,
  ylim = NULL,
  xlab = NULL,
  ylab = NULL,
  ...
)
# S3 method for pwb_day
plot(
  x,
  type = "PlantTranspiration",
  bySpecies = FALSE,
  xlim = NULL,
  ylim = NULL,
  xlab = NULL,
  ylab = NULL,
  ...
)

Value

An ggplot object

Arguments

x

An object of class spwb_day, growth_day or pwb_day.

type

The information to be plotted (see details).

bySpecies

Allows aggregating output by species, before drawing plots. Aggregation can involve a sum (as for plant LAI or transpiration) or a LAI-weighted mean (as for plant stress or plant water potential).

xlim

Range of values for x.

ylim

Range of values for y.

xlab

x-axis label.

ylab

y-axis label.

...

Additional parameters for function plot.
