[R-sig-Geo] Order raster images in a levelplot

[Navinder Singh]

Hi,
Two questions.

1. Does someone have any suggestions on how i can order the sequence of images in a “levelplot" made using rasterVis.
Specifically, i have months i need to arrange in the normal sequence, as the plot currently aligns them in an alphabetical order. Does “levelplot” works the same way as xyplots in lattice?

2. Have there been more developments on the zApply function in the raster package? I am trying to make basic statistical summaries for mean monthly (eg. NDVI values) form a multi annual time series.
How does one go about using the “by" Indexing in this case.

Thanks,
