exclude_from(month, exclude = NULL)

exfr(month, exclude = NULL)

`month`	range of numeric month ids
`exclude`	range or set of months to exclude

These convenience function is provided for the exclusion of months. E.g., .range(exclude_from(-6:10, -11:3)) will yield the monthly values of all parameters for the months previous June (-6) to current October (10), but without the months previous November (-11) to current March (3) in between. While it is also possible to supply arbitrary vectors as month specification, and not only ranges as shown in most of the examples here, this way of excluding e.g. the dormant season is far more convenient.
