R时间序列数据，每天只有工作日 [英] R time series data, daily only working days

问题描述

我使用以下代码：

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

然而，我只想有工作日，怎么办？
（假设1991/1/4是星期一，我想排除：1991/6/4和1991/7/4。
每周）。

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.)

感谢您的帮助。

推荐答案

这是否适合您？ （请注意，它需要安装timeDate包）

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)
