A look at how to load a CSV file, and calculate the mean of a column named "Ozone", which contains NA values. Functionally, the task can be completed in very similar looking code ... except that there are a few helper functions, types, and operators defined in support of the F#.
setwd("~/dev/datascience/r")
data <- csv.load("hw1_data.csv")
filtered <- data[!is.na(data$Ozone),]$Ozone
mean(filtered)
