Plotting the optimum and cardinal temperatures for crops

Description

Utility function for plotting graphs of thermal preferences for crops. It is necessary to inform the temperature values (minimum, average or maximum).

Usage

optemp(
  VAR,
  crop = NULL,
  verbose = FALSE,
  plot = TRUE,
  ylab = "Meteorological Atribute",
  xlab = "Days After Sowing"
)

Arguments

VAR	The column with air temperature values (minimum, average or maximum).
crop	Parameter to define the culture. Use 'soybean' for soybean crop, 'maize' for maize crop and 'trit' for wheat crop.
verbose	Logical argument. Runs the code silently if FALSE.
plot	Logical argument. Plot a graph of optimal temperatures if TRUE.
ylab	The name of the Y axis.
xlab	The name of the X axis.

Value

Returns the parameters of lower basal and optimum temperature, upper basal and optimum temperature, maximum temperature and average temperature.
