[R] Help on Calculating day differences

[Thorsten Muehge]

Hello R Freaks,
I calculate the difference in days between two events with the following 
litte R expresseion:

T1a <- strptime(T1,"%m/%d/%y %H:%M:%S");
T2a <- strptime(T2,"%m/%d/%y %H:%M:%S");
T1b <- as.Date(T1a);
T2b <- as.Date(T2a);
days <- T2b-T1b;
time <- T2a - T1a;

In the project I would like to calculate only working day.

I the a possibility to count on woring days without weekends?

Is it maybe also possible to skip in addition the national holiday dates?

Thanks a lit for your help
Thorsten

Mit freundlichen Grüßen / Best Regards / С наилучшими
