This function reconstructs the input data according to the Microarray
grid location structure and plots the data according to the user
specified color map.
By default, it will plot the log ratios for 2-dye array and raw
intensity for 1-dye array. It does not work for N-dye (N>2) array at
this time.
Note that if user collapsed the replicates by using 'avgrep' in
read.madata, and then
arrayview will not be available.
The data to be plotted. The length of it must be
equal to the length of the grid locations, .e.g, madata$row and
madata$col. If ratio is a vector, there will be one plot. If ratio
is a matrix, there will be one plot for each column. If ratio is not
provided, link[maanova]{make.ratio} will be called to
calculate the ratios from the original data.
array
A list of arrays to be plotted. This variable is only
valid when ratio is not provided. Whenever ratio is
provided, all columns in ratio will be plotted.
colormap
User specified color map. See
colors for more detail.
...
Other parameters to be passed to
image.
onScreen
A logical value to represent whether to display the
plots on screen or not. If TRUE, x11() (in Unix/Windows) or
macintosh (in Mac) will be called inside the function. Otherwise,
it will plot the figure on the current device. Default is TRUE.

## Not run:
data(kidney)
# arrayview data on screen
arrayview(kidney.raw, array=1)
graphics.off()
# arrayview raw data array 1 and 3 and output to postscript file
postscript(file="kidneyArrayview.ps")
arrayview(kidney.raw, array=c(1,3), onScreen=FALSE)
## End(Not run)
