Description

Plot of the data points and the sample means at each dose

Usage

IsoPlot(x, y, type=c("continuous", "ordinal"), add.curve = FALSE)

Arguments

x
indicates the dose levels
y
is the gene expression for one gene
type
specifies the dose levels to "continuous" or "ordinal". The default is "continous".
add.curve
specifies whether a fitted isotonic regression curve with a likely direction is added or not. The default is FALSE.

Value

Plot of the data points, the sample means for each dose (either as continuous or ordinal), and a fitted isotonic regression curve (optional) is produced.
