[R] number of Mondays

[Carlos Hernandez]

dear All,
i'm trying to calculate the number of Mondays, Tuesdays, etc that each  
month within a date range has. I have time series data that spans 60  
months and i want to calculate the number of Mondays, Tuesdays, Wed,  
etc of each month. (I want to control for weekly seasonality but my  
data is monthly).

Is there an easy way to to this in R? or is there a package i could  
use? i did some quick search in the help files and R sites but could  
not find any answers.

i appreciate any hint you could give,

thanks.

Carlos
