MASHADE procedure

Produces shade plots to display spatial variation of microarray data (D.B. Baird).

Options

SLIDES = factor

Slide to which each DATA unit belongs

SLIST = variate or text

Subset of slides to plot; default * i.e. all

ROWS = factor or variate

Row to which each DATA unit belongs

COLUMNS = factor or variate

Column to which each DATA unit belongs

COLOURS = scalar or variate

Colours to use for the plots

SHADING = string

Shading scale (natural, percentiles); default natu

TITLE = text

Title for the graph

YTITLE = text

Title for the y-axis

XTITLE = text

Title for the x-axis

WINDOW = scalar

Window number for the graphs; default 3

DEVICE = scalar

Device number on which to plot the graphs

GRAPHICSFILE = text

What graphics filename template to use to save the graphs; default *

Parameter

DATA = variates

Values for each shade plot

Description

The data values are supplied, in a variate, using the DATA parameter. The SLIDES option supplies a factor to define the slides. By default a histogram is produced for the data from every one of the slides, but you can set option SLIST to a variate or text to define a subset of the slides to plot. The ROWS and COLUMNS parameters each supply a factor or variate to define the row and column positions within the slides.

The COLOURS option supplies a scalar or variate to define the colours to use for the plots. The default of !(4,2) uses colours ranging from blue to red. The SHADING option chooses whether to allocate the DATA values to shades by percentiles, thus giving similar amounts of each colour on the plots, or by their actual values (the default).

The TITLE, YTITLE and XTITLE options can supply titles for the graph, the y-axis and the x-axis, respectively. The WINDOW option specifies the window to use (by default 3), and the KEYWINDOW option can specify a window for a key (by default there is none). You can use the DEVICE option to plot to a device other than the screen. The GRAPHICSFILE option specifies then supplies a template for the file names.
