我试图从1月到12月3次创建一个月的序列.即.1月2月3月 ...12月1月2月3月....12月1月2月3月....十二月
我试过这段代码
rep(c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sept","Oct","Nov","Dec"),each=3)
但它会产生这样的结果
[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Jan Feb Mar .... Dec Jan Feb Mar ..... Dec Jan Feb Mar ... Dec
