我正在尝试运行bfast :: bfast（）来对2003年的365个观测数据集进行时间序列分析。不幸的是，我总是收到相同的错误消息。感谢您的帮助！
mydata_2003 <- mydata[1:365, ]
# to extract the data for the year 2003 from a dataframe
# (each row one observation)
mydata_2003_ts <- ts(data = mydata_2003$area, start = c(2003, 1),
end = c(2003, 12), frequency = 365)
# convert the data for the year 2003 into a ts-object
mydata_2003_bfast <- bfast(Yt = mydata_2003_ts, season = "dummy",
max.iter = 1)
Error in stl(Yt, "periodic") :
series is not periodic or has less than two periods
