I'm trying to get the 8 hour rolling mean for o3 using the rollingMean function using this code:

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"

But I keep getting this error message: 

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

Any help with this would be greatly appreciated I'm very new to R. Thanks

If you attach mydata from the package using data(mydata), it should work.

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")
