该博客展示了如何使用R语言创建一个从指定日期开始的按月递增的日期序列，并始终结束于每月的最后一天。示例代码演示了两种不同的方法来实现这一目标，适用于数据处理和时间序列分析的场景。

seq(as.Date("2020-02-01"), length=12, by="1 month") - 1
[1] "2020-01-31" "2020-02-29" "2020-03-31" "2020-04-30" "2020-05-31" "2020-06-30" "2020-07-31" "2020-08-31" "2020-09-30" "2020-10-31" "2020-11-30" "2020-12-31"

ymd("2020-02-01")+ months(0:12)-days(1)
