Let’s take a look at the early voting data for Harris County Since I already have a bunch of data for Harris county precincts and zipcodes, why not make some use of it? path <- "/home/ajackson/Dropbox/Rprojects/Voting/" BBM <- read_csv(paste0(path, "Cumulative_BBM_1120.csv"), col_types = "ccccccccccccccccccccccccccccccccccccccccc") BBM <- BBM %>% mutate(ActivityDate=mdy_hms(ActivityDate)) %>% mutate(ActivityDate=force_tz(ActivityDate, tzone = "US/Central")) %>% select(ElectionCode:ActivityDate) %>% mutate(Ballot_Type="Mail") EV <- list.files(path=path, pattern="Cumulative_EV_1120_1*", full.names=TRUE) %>% map_df(~read_csv(.

Harris County COVID-19 data I have a very nice (I hope) dataset consisting of number of positive COVID-19 cases per day in Harris county by zipcode.

Initial look First off, let’s explore the data for issues, and for ideas about what might be interesting.

Miscellaneous analyses related to the Covid-19 pandemic After reading the paper this morning about a county nearby (Houston county) with zero reported cases, I got curious. What does the distribution of test coverage look like, i.e., number of tests per capita? And also, what is the rate of tests that come back positive? So let’s look at the data.

We like to walk. When the weather cooperates, we can easily get in 5 or more miles in a day just walking around the neighborhood. We walk to the bank, to the grocery store, the hardware store, or just around the ’hood. There are two huge irritants on our walks.

Solar Panels in Houston

Having bought solar panels myself a couple of years ago, and realizing that the city permit database could be used to find most installations, I decided that it would be interesting to look at the recent history and a few other facets of residential solar panel installations. The first step is to download the structural permit data as a CSV file from the city open data website.

Introduction TXDoT has available, online, detailed data regarding traffic collisions throughout the state. The data itself must be queried and downloaded manually as CSV files, but that is not too bad. I downloaded the data for Harris county from 2010 to 2018. Database is documented at https://www.txdot.gov/inside-txdot/division/traffic/data-access.html Access is from https://cris.txdot.gov/secure/Share Log on and download one year at a time.
