Hi there,
I am having problem of matching string. what i want is when i type a date such as 2010-11-30, the function will return the day (monday, tuesday, wednesday, thursday, friday or staturday). then i want another function will return true if the return of the day is monday, return false if the return of the day is not monday.
I already find the weekdays(as.Date('2010-11-30')) function which will tell me exactly what day its gonna be. however, i am having problem of return True or False whether or not the return day has matched. 
please help me out. I appreciate.
Bill
P.S the following is the partial codes.if(match(weekdays(as.Date('2010-11-30'), "Monday")==1){print("yes")}
