r - 如何创建特定月份和/或日期序列 "n"次

Question

我正在尝试创建一系列月份1月至12月共3次。 IE。扬二月三月。。。。十二月扬二月三月。。。。十二月扬二月三月。。。。十二月

我尝试了这段代码

rep(c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sept","Oct","Nov","Dec"),each=3)

但它会生成这样的结果

[1] "Jan"  "Jan"  "Jan"  "Feb"  "Feb"  "Feb"  "Mar"  "Mar"  "Mar"  "Apr"  "Apr"  "Apr" 
[13] "May"  "May"  "May"  "Jun"  "Jun"  "Jun"  "Jul"  "Jul"  "Jul"  "Aug"  "Aug"  "Aug" 
[25] "Sept" "Sept" "Sept" "Oct"  "Oct"  "Oct"  "Nov"  "Nov"  "Nov"  "Dec"  "Dec"  "Dec" 

但我想要一月二月三月...十二月一月二月三月...十二月一月二月三月...十二月

谢谢哈沙德

Answer 1

我们可以使用month.abb代替c('Jan', 'Feb')等。

 rep(month.abb, 3)

完整月份名称

 rep(month.name, 3)
