R Documentation

Model fit plotting

Description

Plot maximum likelihood curves fitted with drda.

Usage

## S3 method for class 'drda'
plot(x, ...)

Arguments

`x`	`drda` object as returned by the `link[drda]{drda}` function.
`...`	other `drda` objects or parameters to be passed to the plotting functions. See 'Details'.

Details

This function provides a scatter plot of the observed data, overlaid with the maximum likelihood curve fit. If multiple fit objects from the same family of models are given, they will all be placed in the same plot.

Accepted plotting arguments are:

base: character string with the base used for printing the values on the x axis. Accepted values are 10 for base 10, 2 for base 2, e for base e, or n (default) for no log-scale printing.
col: curve color(s). By default, up to 9 color-blind friendly colors are provided.
xlab, ylab: axis labels.
xlim, ylim: the range of x and y values with sensible defaults.
level: level of confidence intervals (default is 0.95). Set to zero or a negative value to disable confidence intervals.
midpoint: if TRUE (default) shows guidelines associated with the curve mid-point.
plot_data: if TRUE (default) shows in the plot the data points used for fitting.
legend_show: if TRUE (default) shows the legend.
legend_location: character string with custom legend position. See link[graphics]{legend} for possible keywords.
legend: custom labels for the legend model names.
show: If TRUE (default) a figure is plotted, otherwise the function returns a list with values to create the figure manually.
