### change "pasteBinUrl" if theymos updates data

### functions
date.func <- function(x) ISOdate(1970,1,1)+ x$Unixtime

### download data
uniqueID <-  gregexpr("[1-9]", pasteBinUrl)[[1]]
reddit <- fromJSON(paste("http://pastebin.com/download.php?i=", substr(pasteBinUrl, uniqueID[1], uniqueID[2]), sep=''))

### format data sets for plotting
