[BioC] mouseData in heatmap of metagenomeSeq package

[guest [guest]]

Dear Bioconductor users,

I would like to plot heatmap with metagenomics dataset, I have 48 mouse samples that were distributed into 8 groups. I copied my dataset as the same format to metagenomeSeq directory for importing the dataset. Everything seems fine till I tried to plot heatmap. I copied the scripts from the tutorial.

> data(mouseData)
> trials = pData(mouseData)$diet
> heatmapColColors = brewer.pal(12, "Set3")[as.integer(factor(trials))]
> heatmapCols = colorRampPalette(brewer.pal(9, "RdBu"))(50)
> # plotMRheatmap
> plotMRheatmap(obj = mouseData, n = 200, cexRow = 0.4, cexCol = 0.4, trace = "none", col = heatmapCols, ColSideColors = heatmapColColors)


When I looked at the heatmap, it is not my dataset, it is still from the example dataset. When I checked on the scripts again, I didn't see any script to help build mouseData with the new dataset. COuld you instruct how I load my dataset into mouseData? or any other solutions?

Thanks a lot, I do appreciate it.
