[BioC] error on heatmap

[guest [guest]]

Dear Biocondutor users,

I would like to plot the heatmap using metagenomeSeq package, I used the same example dataset and same R scripts from package tutorial, but it has the error message when I do the heatmap. Please see R scripts and error message below:

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

Error in heatmap.2(mat2, ...) : lazy-load database 'P' is corrupt
In addition: Warning messages:
1: In heatmap.2(mat2, ...) : restarting interrupted promise evaluation
2: In heatmap.2(mat2, ...) : internal error -3 in R_decompress1

Thanks for the help, I really appreciate it.
