支線劇情，劇情無厘頭

我有一個所謂的「降雨」的數據集，前幾行支線劇情，劇情無厘頭

Year Month  Date cuftsec   lsec log10lsec 
1 1997 January 1/15/1997 57.100 3.360907e-02 -1.473544 
2 1997 February 2/15/1997 13.800 8.122686e-03 -2.090300 
3 1997 March 3/15/1997 5.100 3.001866e-03 -2.522609 
4 1997 April 4/15/1997 2.210 1.300812e-03 -2.885786 
5 1997  May 5/15/1997 0.469 2.760590e-04 -3.558998 
6 1997  June 6/15/1997 0.000 5.886000e-09 -8.230180

我想獲得日期和log10lsec的線圖。當我嘗試

with(rainfall, plot(x = Date, y = log10lsec, type = "l"))

我得到一個積分的點（好像type =「l」不在那裏）。

如果我設置了另一個圖然後添加一行，例如與

with(rainfall, plot(x = Date, y = log10lsec)) 
with(rainfall, lines(x = Date, y = log10lsec))

我得到一個荒謬的線圖，以看似隨機的順序連接點。

dput（頭（降雨））產量：

structure(list(Year = c(1997L, 1997L, 1997L, 1997L, 1997L, 1997L

什麼是類'Date'的？這是一個因素嗎？ – 2013-03-09 21:44:28

請讓你的例子可重現。我們不知道「設置另一個圖」的含義。 – 2013-03-09 21:44:56

您可以通過發佈'dput（降雨）'的輸出來使您的示例具有可再現性。 – 2013-03-09 21:51:03

我覺得這個問題正是Date是一個因素。這似乎工作：

with(dat,plot(as.Date(Date,format="%m/%d/%Y"),log10lsec,type="l"))

，或者如果你想轉換永久日期，

dat <- transform(dat,Date=as.Date(Date,format="%m/%d/%Y")) 
with(dat,plot(log10lsec~Date,type="l"))
