Error in finding function of openair

[sgulia]

Hi

I tried to work on the openair package using Rstudio. I have installed the openair package and update also many time, but still getting problem in finding the function and came out with following error. I need your help in solving this.

polarPlot(mydata,pollutant="pm25",ws="ws",wd="wd",type="default",statistic="mean",resolution="normal",cols="default",angle.scale=315,key.position="right",key=TRUE,auto.text=TRUE)
Error in polarPlot(mydata, pollutant = "pm25", ws = "ws", wd = "wd", type = "default", :
could not find function "polarPlot"
calcPercentile(mydata, pollutant = "PM25", avg.time = "month",
percentile = 50, data.thresh = 0, start = NA)
Error in calcPercentile(mydata, pollutant = "PM25", avg.time = "month", : **
** could not find function "calcPercentile"

Do you get any error message when installing/updating? Have you remembered to load the package before using the function?
