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.
