Order raster images in a levelplot
Hi,
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?
levelplot methods defined in rasterVis are based on lattice graphics. Most of the arguments provided by lattice::xyplot and lattice::levelplot are also available. For this issue you could try these arguments: perm.cond, index.cond, as.table. All of them are described in the help page of lattice::xyplot.
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.
Could you post a reproducible example? I have used zApply for similar tasks without problems. Best, Oscar.
