In SamGG/made4: Multivariate analysis of microarray data using ADE4

Description

Returns an index of the top n maximum and minimum values in 2 columns of a matrix or data.frame.

Usage

genes(dudivar,n=5, axis1=1, axis2=2)

Arguments

dudivar	a data frame or matrix with at least two columns, containing the x,y coordinates.
axis1	the column number for the x-axis.
axis2	the column number for the y-axis.
n	n is the number of genes to be extracted.

Details

Genes returns an index of the "top" variables at the ends of the x and y axes. Genes is not normally called by the user but is called by plotgenes()

If you wish to return a table or list of the top genes at the end of an axis, use the function topgenes.

Thanks to Miss Jess Mar for helping on this function.
