Question

I am using the following code:

dates<-seq(as.Date("1991/1/4"),as.Date("2010/3/1"),"days")

However, I would like to only have working days, how can it be done?
(Assuming that 1991/1/4 is a Monday, I would like to exclude: 1991/6/4 and 1991/7/4.
And that for each week.)

Thank you for your help.

Answer 1

Would this work for you? (note, it requires the timeDate package to be installed)

# install.packages('timeDate')
require(timeDate)

# A ’timeDate’ Sequence
tS <- timeSequence(as.Date("1991/1/4"), as.Date("2010/3/1"))
tS

# Subset weekdays
tW <- tS[isWeekday(tS)]; tW
dayOfWeek(tW)
