[R] Day Count Convention

2007-08-31 Thread Andreas Wittmann
Hi everybody,

i'm working on the next version of the CreditMetrics package. So i have 
the question, are there any functions or packages which have have the 
functionality to calculate dates with a certain day count convention 
like act/360 or 30/360? Intensive search in the r-help archive or in the 
manuals did not bring any solution.

thanks everybody for some help.


best regards

Andreas

[R] Review process for new packages

2006-10-17 Thread Andreas Wittmann
Hi all, 

i'm currently working on a creditmetrics package which includes functions for 
computing the credit risk model creditmetrics. I guess it would be finished in 
a few days. 

My question now is, does there exist some review process before sending it to 
ctan or is it reviewed after having sended it?


best regards
Andreas
