I'm trying to plot smooth trend using smoothTrend in OpenAir but I'm having
problems.

I used the following code.
---------------------------------------------------------------------------------
#Set my working dir to the dir with my files
setwd("c:/R")

#Load the openair library
library(openair)

#Load the data
mydata <- read.table("MCNP-pH.csv", header=TRUE, sep=",",)

#Plot the data
smoothTrend(mydata, pollutant = "pH")
---------------------------------------------------------------------------------


I get the following error:
Error in seq.int(0, to0 - from, by) : 'to' must be finite
In addition: Warning messages:
1: In min.default(c(NA_real_, NA_real_, NA_real_, NA_real_, NA_real_,  :
  no non-missing arguments to min; returning Inf
2: In max.default(c(NA_real_, NA_real_, NA_real_, NA_real_, NA_real_,  :
  no non-missing arguments to max; returning -Inf
>

A copy of the data can be found at
www.doylesdartden.com/e/MCNP-pH.csv

Any suggestions??

Thank you
David
