Description Usage Arguments Details Author(s) See Also Examples

Illustrate the Langmuir Isotherm for selected probe set.

1	plotILM(object,y,z,...)

`object`	An object of type `ILM`
`y`	A probe set
`z`	The name of a sample
`...`	Graphical parameters can be given as arguments to `par`

plotIntens plots one graph for each CEL-file. Note that it is only possible to plot one probe set at a time (if y (or z) is a vector, only the first value is used). If y=NULL or z=NULL, there is no output. Optional plot.error argument (numeric) can be used to define the illustration of the variability. plot.error=1 computes the error on the log scale. plot.error=2 (default value) computes the error on the concentrations. plot.error=3 computes the error on the concentrations, for 2 intervals. Note that error curves can only be plotted if concentration is higher than error (negative concentration does not exist!).
