Time aggregation functions not drop time dimension
This issue is regarding time aggregation functions:
- PeriodAccumulation
- PeriodMean
- PeriodMax
- PeriodMin
- PeriodVariance
- AccumulationExceedingThreshold
- TotalSpellTimeExceedingThreshold
- TotalTimeExceedingThreshold
Current behaviour
Now, when a time dimension is aggregated, it drops.
exp <- CSTools::lonlat_prec_st
dim(exp$data)
exp$attrs$Dates <- Reorder(exp$attrs$Dates, c(2,1))
res <- CST_PeriodAccumulation(data = exp, time_dim = 'ftime',
start = list(10, 03), end = list(20, 03))
dim(res$data)
# Same for Dates
Development needed
I think that it would be good to not drop the accumulated dimension since the common structure for a climate data array is with forecast time dimension. As an example, the function from CSTools: SaveExp, needs to add a time dimension of lenght 1 internally to work.
