,
between is a thin wrapper for the between function of data.table::between.
It is equivalent to x >= lower & x <= upper when incbounds=TRUE, or x > lower & y < upper when FALSE. In comparison
with dplyr::between, it doesn't loose the class of its argument, and it's more appropriate for manipulating
the column .sample. For more information and the description of the arguments, see data.table::between.
