amap: Heatmap and dendrogram from associations between all pairs of variables.

Description

Clusters variables in a datafrome using dist = 1-A and plots a heatmap with cluster dendrogram attached.

Usage

amap(dataSet, palette, corAdjusted, method, title, ...)

Arguments

dataSet

the n x m data frame representing n samples of the m variables.

palette

colour palette to use for the heatmap.

corAdjusted

a flag which if set causes bi-variate A scores to be mutiplied by the sign of the same bi-variate correlation. This gives a direction to the association. defaults to FALSE.

method

the method to use for correlation association as performed by cor, one of "pearson", "spearman", "kendall". The default is "spearman".

title

a main title for the heatmap plot.

passed on to graphics routines ...

Value

Returns nothing.

Details

uses heatmap.2 from the gplots package to display a heatmap and associated dendorgram with bi-variate scores provided by matie's A value. If required these scores can be expanded into the range [-1,1] through multiplication by the sign of the corresponding bi-variate correlation score.
