rb3 options
rb3 uses base::options
to allow user set global options that affect the
way the package works and display its alerts.
- rb3.cachedir
rb3 cache folder is named
rb3-cache
and it is created inside the directory returned bybase::tempdir
. Since it is changed for every new session it is interesting to use the same directory for cache across sessions. Once the optionrb3.cachedir
is set the files are always cached in the same directory. This is very useful to build a historical data. Historical time series can be loaded directly from cached files.- rb3.clear.cache
Some files have invalid content returning NULL data. Every downloaded file is stored in the cache folder. If
rb3.clear.cache
is TRUE these invalid files are remove once they are detected. It helps with keeping only files with valid content in the cache folder.- rb3.silent
rb3 default behavior on communicating users what's going on is total transparency. So, it displays many alert messages to inform users many of the details. On the other hand, this behavior can be sometimes annoying. The option
rb3.silent
can be set toTRUE
in order to avoid that the alerts be displayed.
