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 class 'spwb_day'
plot(
  x,
  type = "PlantTranspiration",
  bySpecies = FALSE,
  xlim = NULL,
  ylim = NULL,
  xlab = NULL,
  ylab = NULL,
  ...
)

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

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

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.

• "GrossPhotosynthesis": Gross photosynthesis rate per dry weight.

• "MaintenanceRespiration": Maintenance respiration cost per dry weight.

• "RootExudation": Root exudation rate per dry weight.

• "LabileCarbonBalance": Labile carbon balance per dry weight.

• "StarchLeaf": Starch concentration in leaves.

• "SugarSapwood": Sugar concentration in sapwood.

• "StarchSapwood": Starch concentration in sapwood.

• "SugarTransport": Phloem sugar transport rate.

Value

An ggplot object

Note

Only for soil plant water balance simulations using transpirationMode = "Sperry" or transpirationMode = "Sureau". This function can be used to display subdaily dynamics of corresponding to single days on spwb runs, if control option subdailyResults is set to TRUE. See also option subdaily in plot.spwb.

Examples

#Load example daily meteorological data
data(examplemeteo)

#Load example plot plant data
data(exampleforest)

#Default species parameterization
data(SpParamsMED)

#Define soil with default soil params (2 layers)
examplesoil <- defaultSoilParams(4)

#Switch to 'Sperry' transpiration mode
control <- defaultControl("Sperry")

#Enable subdaily results for plotting
control["subdailyResults"] <- TRUE

#Initialize model inputs
x2 <- spwbInput(exampleforest,examplesoil, SpParamsMED, control)

#Simulate one day only
d <- 100
date <- examplemeteo$dates[d]
meteovec <- unlist(examplemeteo[d,])
sd2 <- spwb_day(x2, date, meteovec,
              latitude = 41.82592, elevation = 100, slope= 0, aspect = 0)

#Display transpiration for subdaily steps
