Count of influenza-like illness for selected US states

Software requirements

I use R to manipulate the data and produce the charts. I use data.table, ggplot2 and scales for this analysis. To download these packages, open R console and enter the following:

pkgs <- c("data.table", "scales", "ggplot2")

for(i in seq_along(pkgs){
  if(!nzchar(system.file(package = "pkgs[[i]]))) install.packages(pkgs[[i]])
}

The data/process_data.R file reads the raw data and manipulate it to use in analysis/analysis.R. So the script flow is data/process_data.R --> analysis/analysis.R, pretty simple!
