didn’t use the whole data to calculate “K” if parameter “nclusters” is
NULL.; Add missing output dimension names
- Clim(): Correct the output dimensions for some cases; allow dat_dim
to be NULL; obs doesn’t need to have dat_dim.

instead of an array
- Load(): Bugfix for R >= 4.0.0 regarding list and vector
confusion
- PlotLayout(): Bugfix when param “var” is a list

has a spatial mean of zero. “space_dim” is deprecated and replaced by

before correlation or calculate the correlation for individual
member.

- Reorder(): Improve efficiency.
- Indices functions take the case without ‘memb_dim’ into
consideration. The climatology calculation for the anomaly is
member-dependent if member exists.

consistent.
- Improve Season() performance by using apply() when ‘ncores’ is not
bigger than 1
s2dv 0.0.1 (Release date:
2020-02-07)
- The package is the advanced version of package ‘s2dverification’,
adopting the regime of package ‘multiApply’ for all the analytic
functions. Most of the other functions for plotting and data retrieval
in ‘s2dverification’ are also preserved in this package.
- Because of the adoption of ‘multiApply’ regime, the functions work
well with package ‘startR’.
- All the packages mentioned above are developed by BSC-CNS.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
