我有这些数据:

看起来很好,但是当我尝试使用openair绘制数据时,为什么会出现此错误?

timePlot(dataF, pollutant = c("PM"), group = TRUE, avg.time = "default")

Error in object[[name, exact = TRUE]] : subscript out of bounds
In addition: Warning message:
In checkPrep(mydata, vars, type, remove.calm = FALSE) :
  Detected data with Daylight Saving Time, converting to UTC/GMT

数据有什么问题?有什么想法吗?

答案 0 :(得分:3)

我想您想使用PMdate值与timeplot()值进行对比。 date中的所有日期时间值都属于同一天"2016-09-01",而key_date则指定在timeplot()下。

data.frame说明https://www.rdocumentation.org/packages/openair/versions/0.3-8/topics/timePlot 指定数据必须为date,且date列,在所考虑的示例中为ymd_hms

因此,我使用lubridate包中的函数date来处理PM中的日期时间格式,并强制as.numeric中的值为{require(lubridate) library(lubridate) dataF <- data.frame(key_date = c("2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01", "2016-09-01"), date = ymd_hms( c("2016-09-01 00:00:00", "2016-09-01 01:00:00", "2016-09-01 02:00:00", "2016-09-01 03:00:00", "2016-09-01 04:00:00", "2016-09-01 05:00:00", "2016-09-01 06:00:00", "2016-09-01 07:00:00", "2016-09-01 08:00:00", "2016-09-01 09:00:00", "2016-09-01 10:00:00", "2016-09-01 11:00:00", "2016-09-01 12:00:00", "2016-09-01 13:00:00", "2016-09-01 14:00:00", "2016-09-01 15:00:00", "2016-09-01 16:00:00", "2016-09-01 17:00:00", "2016-09-01 18:00:00", "2016-09-01 19:00:00", "2016-09-01 20:00:00", "2016-09-01 21:00:00", "2016-09-01 22:00:00", "2016-09-01 23:00:00")), PM = as.numeric(c("10.9", "9.8", "9.9", "14.1", "13.6", "16.5", "15", "18.5", "18", "17", "16.6", "12", "12.1", "18.1", "15.9", "15.9", "16.9", "21.6", "23.5", "40.7", "16.6", "12.7", "12.4", "12.2")), site = c("LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2"), code = c("LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2", "LW2"), airport = c(NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_, NA_integer_), ws = c(NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_), wd = c(NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_), tempi = c(NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_), humidity = c(NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_, NA_real_) ) 1}}到达

dataF

我们检查str(dataF) 'data.frame': 24 obs. of 10 variables: $ key_date: Factor w/ 1 level "2016-09-01": 1 1 1 1 1 1 1 1 1 1 ... $ date : POSIXct, format: "2016-09-01 00:00:00" "2016-09-01 01:00:00" "2016-09-01 02:00:00" ... $ PM : num 10.9 9.8 9.9 14.1 13.6 16.5 15 18.5 18 17 ... $ site : Factor w/ 1 level "LW2": 1 1 1 1 1 1 1 1 1 1 ... $ code : Factor w/ 1 level "LW2": 1 1 1 1 1 1 1 1 1 1 ... $ airport : Factor w/ 0 levels: NA NA NA NA NA NA NA NA NA NA ... $ ws : num NA NA NA NA NA NA NA NA NA NA ... $ wd : num NA NA NA NA NA NA NA NA NA NA ... $ tempi : num NA NA NA NA NA NA NA NA NA NA ... $ humidity: num NA NA NA NA NA NA NA NA NA NA ...

的结构
timePlot(dataF, pollutant = "PM", group = TRUE, avg.time = "default", lty = 1)
dev.off()

现在我们绘制

if (item.limit != null || item != ' ' && now.isAfter(dateLimit) ) {
