After a breif break from classes, but not a break from R, I have started #5 and #6.  I sent the below message to all members in those classes. Everyone in this group should be a moderator.  If you notice any new requests come in, please approve and promote the requester.

I would like to get this group started up.  Any interest in a study session this week?

-------------------------------Begin Message--------------------------------
In the first class we attempted to start a study group here in Chicago that never really got off of the ground.  As the content gets more difficult and expansive, I think it is a good idea to try and restart this group.  If anyone is interested, I have created a google group at https://plus.google.com/communities/108918450770950636710 .  I am not certain about the googleplus group url format, so if the above does not work, the name of the group is " Chicago Coursera Data Science and Kaggle Team ".

US PM25 numbers split into 5 distinct groups by color based on quantity.

url<-"http://www.epa.gov/ttn/airs/airsaqs/detaildata/501files/RD_501_88101_2012.zip"

filename<-unlist(strsplit(url,'/'))[NROW(unlist(strsplit(url,'/')))]
fname<-paste0(datafolder,filename)
if(!file.exists(fname)){

download.file(url,paste0(datafolder,filename),method='curl' )
}
#unzip  and change fname variable
fname<-'c:\\location\\of\\data.csv
pollution<-read.csv(fname, colClasses=c('numeric','character','factor','numeric','numeric'))

pollution$pm25group<-cut(pollution$pm25, breaks=quantile(pollution$pm25, probs=c(0.00,0.25,0.50,0.75,1.00)))

plot(y=pollution$latitude, x=pollution$longitude, col=pollution$pm25group, cex=.4, pch=20)

As a Chicago native in the data science certificate, I pulled and cleaned all Chicago crime data Sive 1/1/2001 and created the following map. Each point is a crime (red for violent, green for drug, blue for sexual) at .005 alpha using ggplot2. The image below is the result along with individual images per crime type.

Tyler,

Actually it turned out I made this a lot harder to do than It had to be.  I did not back this with any gis data, but that was because it had so many data points that the map became apparent from the data itself.  I'm not sure if you remember the pm25 data set from the exploratory class.  Check out the image ill post in a few minutes.  Ill include the R code with it.  Same thing applies though.  there is enough data that the map becomes apparent.  I am currently reading a book called "Data Driven Security".  It shows very easy ways to back the GIS data. by Country, state and even down to the county level.

You know, I don't know why I didn't think of this before, but I can host at my office. There is a Starbucks right across the street (hence my drinking problem) and tons of conference room. It is in the west loop at Jefferson and lake with a parking lot depending on the time of day and plenty of street parking.
