Living in the Bay Area has led me to think more and more about real estate (and how amazingly expensive it is here…)  I’ve signed up for trackers on Zillow and Redfin, but the data analyst in me always wants to dive deeper, to look back historically, to quantify, ...

I’ve started doing some basic analysis on Oakland real estate prices over the past decade (multi-tenant buildings only).  There’s still a lot to unpack here, but I’m only able to investigate this 30 minutes at a time (new dad life), so I’ll be making lots of short ...

Choroplethr is great to use straight out of the box, but sometimes you’ll want to fix up some of the details.  In a previous post, I showed how to modify the color scheme.  Now I’ll explain how to set up customized bins when using choroplethr.  If you just ...

The choroplethr package is outstanding and fairly easy to use, but some functionality is not obvious.  The built-in color scheme is quite good, but you might want to switch colors at some point.  My first attempt at changing the color scheme can be found below (previous post has basic code ...

Previously, I posted a short post about recent detached single house prices in San Leandro and Hayward areas.  I received a little more data (sales data from the past month), so I thought it would be a good time for … Continue reading →

I know that many people consider for-loops the devil, but every so often I get lazy and I use them in the office.  Sometimes it’s nice to keep track of how far through the loop R has gone.  A couple years … Continue reading →

I’ve done a previous post about the salaries of data scientists, but now I’m going to look at one of the negative sides of all the high salaries generated by the tech field in the Bay Area – real estate prices. A … Continue reading →

I was recently interviewed by Todd Wasserman (an editor for Mashable) for an article about data science.  Todd asked me a bunch of simple questions about the day-to-day life of a data scientist.  I described my experiences working for a Bay … Continue reading →
