In USGS-R/gsplot: Geological Survey Plotting

gsplot curve

Description

Plot a mathematical function of x on a new or existing plotting region.

Usage

curve(object, ...)

Arguments

object	gsplot object
...	Further graphical parameters may also be supplied as arguments. See 'Details'.

Details

Additional graphical parameter inputs:

• expr mathematic function in terms of x

• from x value indicating the beginning of the plotted function

• to x value indicating the end of the plotted function

• n integer, number of x values at which to evaluate expr

• add logical, TRUE=add to existing plot, FALSE=create new plot (default)

• xlim vector indicating the lower and upper x values of the plotting window

• ylim vector indicating the lower and upper y values of the plotting window

• type plot type, where 'l'=line, 'p'=point, etc

• log string indicating axes to have a log scale, where ""=none, "x"=x-axis, "y"=y-axis, and "xy"=both axes

• col line color

• lty line type

• lwd line width

• legend.name name that appears in the legend, see legend for more legend parameters
