mxy.abs.plot {OLIN} | R Documentation

## Generation of MXY plots of absolute values

### Description

This function produce a MXY plot of absolute values of M including a colour bar.

### Usage

    mxy.abs.plot(V,Ngc,Ngr,Nsc,Nsr,color.lim,color="red",xlab="Columns",ylab="Rows",...)

### Arguments

`V` | vector of positive values
`Ngc` | number of columns for the grid matrix
`Ngr` | number of rows for the grid matrix
`Nsc` | number of columns for the spot matrix
`Nsr` | number of rows for the spot matrix
`color.lim` | limits of color range for MXY plot
`color` | color to be used for plot: “red” (default) or “green”
`xlab` | label of x -axis of MXY plot
`ylab` | label of y-axis of MXY plot
`...` | Further optional graphical parameter for the `image` function generating the MXY plot

### Details

The function `mxy.abs.plot` is similar to function `mxy.plot`. Details can therefore be found at `mxy.plot`. Two differences, however, exist: First, `mxy.abs.plot` plots the absolute value of V and second, “red” (default) or “green” can be chosen as colour of plotting. Hence, `mxy.abs.plot` facilitates the inspection of spatial artifacts in single fluorescence channels.
