如何讓R包Openair中的rollingMean函數工作？

Question

我正在嘗試使用以下代碼使用 rollingMean 函數獲取 o3 的 8 小時滾動平均值：

mydata <- rollingMean(mydata, pollutant = "o3", hours = 8)
breaks <- c(0, 34, 66, 100, 121, 141, 160, 188, 214, 240, 500)
labels <- c("Low.1", "Low.2", "Low.3", "Moderate.4", "Moderate.5", "Moderate.6",
"High.7", "High.8", "High.9", "Very High.10")
calendarPlot(mydata, pollutant = "rolling8o3",breaks = breaks, labels = labels, cols = "jet", statistic = "max"

但我不斷收到此錯誤消息：

Error in strsplit(interval, split = " ") : non-character argument
In addition: Warning message:
In diff(as.numeric(unique(dates[order(dates)]))) :
  NAs introduced by coercion

對此的任何幫助將不勝感激我對 R 很陌生。謝謝

如果您使用data(mydata)從包中附加mydata ，它應該可以工作。

library(openair)
data(mydata)
mydata <- rollingMean(mydata, pollutant = "o3", hours = 8)
breaks <- c(0, 34, 66, 100, 121, 141, 160, 188, 214, 240, 500)
labels <- c("Low.1", "Low.2", "Low.3", "Moderate.4", "Moderate.5", "Moderate.6",
            "High.7", "High.8", "High.9", "Very High.10")
calendarPlot(mydata, pollutant = "rolling8o3",breaks = breaks, labels = labels, cols = "jet", statistic = "max")
