Dear All,
Firstly I would like to thank you all for the excellent advice that you have given me as I process my single-colour Agilent data using the R package "Agi4x44PreProcess".
I am trying to build the expression set, and would like to plot a heatmap showing the 100 greater variance genes. The first time I ran the function:
esetPROC = build.eset(ddPROC, targets, makePLOT = TRUE, annotation.package = "notAnnPack"), R returned:
Error in HeatMap(exprs(esetPROC), size, maintitle) :
could not find function "maPalette"
I googled and found that maPalette is a feature of marray, and so I installed the most recent version of marray. Now when I run the same command (having also loaded the library "marray"), I get the error:
Error in HeatMap(exprs(esetPROC), size, maintitle) :
could not find function "heatmap.2"
I have tried searching for advice on this but can only find help on how to alter the output of the heatmap, rather than the commands. Have I confused the software by loading the "marray" package? Should I have installed additional packages to plot the heatmap, or is this a general bug? FYI, my version of R is R 2.10.1
Many thanks in anticipation of your help.
With Very Best Wishes
