raster: stackApply problems..

I run the example with clusterR: no_cores <- parallel::detectCores() -1 raster::beginCluster(no_cores) ?????? res <- raster::clusterR(inp, raster::stackApply, args = list(indices=c(2,2,3,3,1,1),fun = mean)) raster::endCluster() And the result is: > res...

This is not a reasonable solution. It is not efficient to run stackapply twice to get the right names. Each execution can take hours. ???? 20/11/2019 3:30 ?.?., ? Frederico Faleiro ??????: > Hi Leonidas, > > both results are in the same order...

Thank you for your help! I tried to fix stackApply according to your instructions. Now the indices of names are the same and consistent with indices enumeration (gist for validation and tests: https://gist.github.com/kokkytos/93f315a5ecf59c0b183f9788754bc170). I've...

I added raster::zApply in my tests to validate the results. However, the indices of the names of the results are different now. Recall that the goal is to calculate from a raster stack time series the mean per day...

Why do they seem logical since they do not match? Check for example index 1 (Sunday). The results are different for the three processes > stackapply_mean class????? : RasterBrick dimensions : 300, 300, 90000, 7? (nrow, ncol, ncell, nlayers) resolution : 500, 500...

Thank you! The problem is not with the resulting values ??but with the index mapping. Values ??are correct in all three cases. As I wrote in a previous post in the thread (https://stat.ethz.ch/pipermail/r-sig-geo...

Ok, I think it's a bug and I'd like your help to confirm this. When the x parameter (a raster stack in this case) of stackApply is quite heavy, then the result of the stackApply is written to...

Thank you Jon! In fact, that's how I thought it worked. And that's how it worked for me all the time! But recently, doing some manual checks on some indices I couldn't confirm it ... I tried to...
