rcdo (development version)

CRAN release: 2025-07-07

Adds caching support in cdo_execute() and cdo_execute_list() as well as cache management with cdo_cache_set() and cdo_cache_unset().
Global options are now not replaced by default if an options argument is supplied. The new options_replace controls this behaviour. If it’s FALSE, then global options, operation options and argument options are all concatenated (duplicated options are not checked for). If it’s TRUE, then only the argument options are used, even if they are NULL (which implies, no options). This is potentially a breaking change.

CRAN release: 2025-05-16

Improved performance of command building by only checking the cdo version installed when needed and also caching the result per session.

Added options management. cdo_options_use() will use options for an operation. cdo_option_set() will set global options to use for all operations. cdo_options_clear() will clear the global options.
The new cdo_operator() allows the user to define an arbitrary operator in case the some operator is missing in the package. Operators are run with the cdo() function.
Added operators with zero outputs.
By default, temporary files output are deleted when not accessible from the R session.
Adds change operators.
Adds cdo_execute_list() to execute a list of cdo operations. This is the preferred way of applying operations to a set of files since it preserves ephemeral files correctly.
