Plot Dose-Effect Experiments

Description

Plot dose-effect experiments on the log10-probit scale.

Usage

plotDELP(DEdata, xlab = "Dose", ylab = "Affected  (%)",
  xlim = range(DEdata$dose[DEdata$dose > 0], na.rm = TRUE), ylim = c(0.1,
  99.9), grid = TRUE, ...)

Arguments

DEdata

A data frame of dose-effect data (typically, the output from dataprep) containing at least five variables: dose, pfx, log10dose, bitpfx, fxcateg.

xlab

A character scalar, the title for the dose (x) axis, default "Dose".

ylab

A character scalar, the title for the affected (y) axis, default "Affected (%)".

xlim

A numeric vector of length two giving the x coordinate range for dose, default range(DEdata$dose, na.rm=TRUE).

ylim

A numeric vector of length two giving the y coordinate range for affected (%), default c(0.1, 99.9). Observed effects beyond this range will be plotted at the limits of this range using an open symbol.

grid

A logical scalar indicating if a background grid should be plotted, default TRUE.
