[R-sig-finance] Problems with monthly sequences

[Diethelm Wuertz]

Many thanks to Gabor for this comment.

For calendar tasks I have written a report (44 pages)  which may be 
helpful for
many calendar manipulations using Rmetrics. Here is the link:

You can also access this "timeDate and timeSeries" white pages from the
Rmetrics home page: www.rmetrics.org

regards
