[1] "200401|200402|200403" "200501|200502|200503" "200601|200602|200603"
This would yield first quarter matches for the years 2004 through 2006.
My plan was to use both splitIt and groupingStrings to be able to create regexps all quarters.
In addition I want it to be flexible enough for me to be able to create matching regexps for monthly, quarterly, se...
