you have to convert your excel file to a .txt file but this should be no problem.

to import your data in R from excel, you've to export your sheet in csv format (tab delimited)
in R :
A <- read.table("your file.csv",header=TRUE,row.names=TRUE,sep="\t")
here's more info and examples : http://www2.warwick....cock/r/heatmap/
