Plot fitted thermal performance curves

Source: R/plot_devmodels.R
plot_devmodels.Rd

Plot the predicted development rates across temperatures based on fitted Thermal Performance Curves (TPCs) for one or several models displayed in facets.

Usage

plot_devmodels(
  temp = NULL,
  dev_rate = NULL,
  fitted_parameters = NULL,
  species = NULL,
  life_stage = NULL
)

Arguments

temp

a vector of temperatures used in the experiment. It should have at least four different temperatures and must contain only numbers without any missing values.

dev_rate

a vector of estimated development rates corresponding to each temperature. These rates are calculated as the inverse of the number of days to complete the transition from the beginning of a certain life stage to the beginning of the following at each temperature. It must be numeric and of the same length as temp.

fitted_parameters

a tibble obtained with fit_devmodels(), including parameter names, estimates, standard errors, AICs, and nls objects (fitted_models) using the nls.multstart::nls_multstart() approach.

species

optional a string of the target species that will constitute the plot title. Must be of type "character".

life_stage

optional a string of the target life stage that will constitute the plot subtitle. Must be of type "character".

Value

A plot with predicted values (development rate) across temperatures for models that have adequately converged using fit_devmodels() function. It's a ggplot object, which can be assigned to a user-defined object.
