curveNoPlot: Adaptation of the curve function (without plot).

In EcotoneFinder: Characterising and Locating Ecotones and Communities

Description

Adaptation of the curve function (without plot).

Usage

curveNoPlot(expr, from = NULL, to = NULL, n = 101, add = FALSE,
  type = "l", xname = "x", xlab = xname, ylab = NULL, log = NULL,
  xlim = NULL, ...)

Arguments

expr	The name of a function, or a call or an expression written as a function of x which will evaluate to an object of the same length as x.
from	the range over which the function will be plotted (start).
to	the range over which the function will be plotted (end).
n	integer; the number of x values at which to evaluate.
add	logical; if TRUE add to an already existing plot; if NA start a new plot taking the defaults for the limits and log-scaling of the x-axis from the previous plot. Taken as FALSE (with a warning if a different value is supplied) if no graphics device is open.
type	plot type: see plot.default.
xname	character string giving the name to be used for the x axis.
xlab	labels and graphical parameters.
ylab	labels and graphical parameters.
log	labels and graphical parameters. See ‘Details’ for the interpretation of the default for log.
xlim	NULL or a numeric vector of length 2; if non-NULL it provides the defaults for c(from, to) and, unless add = TRUE, selects the x-limits of the plot – see plot.window.
...	Additional graphical arguments.

Details

Silently used by SyntheticData and SyntheticDataSeries. Equivalent to the curve function of the graphics package. See the details of the curve function in graphics package for more details.

Value

A vector containing the y values of the gaussian along the gradient.

Examples

gaussian <- function(x) a*exp(-(((x-b)^2)/2*(c^2)))
a <- 60
b <- 250
c <- 0.4
Curve=curveNoPlot(gaussian, from = 1, to = 500, n = 500)
Curve$y
