Change biological functional annotation from list to TRUE / FALSE matrix

1	annotationListToMatrix(annotation, genenames)

`annotation`	functional annotation of genes, as a list
`genenames`	vector of genenames

Converts biological annotation from “list” to “matrix” format. In “list” format, each item in the list is a vector giving genes belonging to a particular biological class. In “matrix” format, each column is a logical vector indicating which genes belong to the biological class. Both BHI and BSI use the TRUE / FALSE matrix format for inputting predetermined biological functional classes.

A logical matrix, where each element indicates whether the gene in row i belongs to the biological functional class of column j

Special thanks to Rainer Machne, who initially suggested this change.

data(mouse)
express <- mouse[1:25,c("M1","M2","M3","NC1","NC2","NC3")]
rownames(express) <- mouse$ID[1:25]
fc <- tapply(rownames(express),mouse$FC[1:25], c)
fc <- fc[-match( c("EST","Unknown"), names(fc))]
fc <- annotationListToMatrix(fc, rownames(express))
