The Carbon Footprint of Food Produced for Consumption

tidyTuesday on the Carbon Footprint of Feeding the Planet The tidyTuesday for this week relies on data scraped from the Food and Agricultural Organization of the United Nations. The blog post for obtaining the data can be found on r-tastic. The scraping exercise is nice and easy to follow and explored a case of cleaning up a very messy data structure. I took this exercise as practice for using pivot_wider and pivot_longer.

Simple Point Maps in R

Mapping Points in R My goal is a streamlined and self-contained freeware map maker with points denoting addresses. It is a three step process that involves: Get a map. Geocode the addresses into latitude and longitude. Combine the the two with a first map layer and a second layer on top that contains the points. From there, it is pretty easy to get fancy using ggplotly to put relevant text hovers into place.

tidyTuesday Measles

tidyTuesday: December 10, 2019 Replicating plots from simplystatistics. One nice twist is the development of a tidytuesdayR package to grab the necessary data in an easy way. You can install the package via github. I will also use fiftystater and ggflags. devtools::install_github("thebioengineer/tidytuesdayR") devtools::install_github("ellisp/ggflags") devtools::install_github("wmurphyrd/fiftystater") tuesdata <- tidytuesdayR::tt_load(2019, week = 50) ## --- Downloading #TidyTuesday Information for 2019-12-10 ---- ## --- Identified 4 files available for download ---- ## --- Downloading files --- ## Warning in identify_delim(temp_file): Not able to detect delimiter for the file.

Trying out Leaflet

International Murders Are among the data for analysis in the tidyTuesday for December 10, 2019. These are made for a map. library(tidyverse) library(leaflet) library(stringr) library(sf) library(here) library(widgetframe) library(htmlwidgets) library(htmltools) options(digits = 3) set.seed(1234) theme_set(theme_minimal()) library(tidytuesdayR) tuesdata <- tt_load(2019, week = 50) murders <- tuesdata$gun_murders There isn’t much data so it should make this a bit easier. Now for some data. As it happens, the best way I currently know how to do this is going to involve acquiring a spatial frame.

Philadelphia Parking Tickets: a tidyTuesday

Philadelphia Map Use ggmap for the base layer. library(ggmap); library(osmdata); library(tidyverse) PHI <- get_map(getbb("Philadelphia, PA"), maptype = "stamen", zoom=12) Get the Tickets Data TidyTuesday covers 1.26 million parking tickets in Philadelphia. tickets <- readr::read_csv("https://raw.githubusercontent.com/rfordatascience/tidytuesday/master/data/2019/2019-12-03/tickets.csv") ## Parsed with column specification: ## cols( ## violation_desc = col_character(), ## issue_datetime = col_datetime(format = ""), ## fine = col_double(), ## issuing_agency = col_character(), ## lat = col_double(), ## lon = col_double(), ## zip_code = col_double() ## ) Two Lines of Code Left library(lubridate); library(ggthemes) tickets <- tickets %>% mutate(Day = wday(issue_datetime, label=TRUE)) # use lubridate to extract the day of the month.

US Census Mapping

Searching and Mapping the Census Searching for the Asian Population via the Census To use tidycensus, there are limitations imposed by the available tables. There is ACS – a survey of about 3 million people – and the two main decennial census files [SF1] and [SF2]. I will search SF1 for the Asian population. library(tidycensus); library(kableExtra) library(tidyverse); library(stringr) v10 <- load_variables(2010, "sf1", cache = TRUE) v10 %>% filter(str_detect(concept, "ASIAN")) %>% filter(str_detect(label, "Female")) %>% kable() %>% scroll_box(width = "100%") name label concept P012D026 Total!

The Generation Squeeze

Hashtag OKBoomer The generational banter that has followed the use of #OKBoomer reminded me of an interesting feature of US population data. I believe it to be true that Generation X has never and will never be the largest generation of Americans. There are tons of Millenials and Baby Boomers alike, though the rate of decline in the latter means that the former are about to surpass them. Or perhaps they have.

Financial Analysis of SEC Reports in R

The Package: finreport The key tool to facilitate the financial analysis of companies that file regular SEC reports of certain forms is finreportr. To make use of it, we must first have R install it and dependencies. To install it, install.packages("finreportr", dependencies=TRUE). The Commands The first command is CompanyInfo(). library(finreportr) CompanyInfo("JPM") ## company CIK SIC state state.inc FY.end street.address ## 1 JPMORGAN CHASE & CO 0000019617 6021 NY DE 1231 383 MADISON AVENUE ## city.

A Quick and Dirty Introduction to R

Some Data I will start with some inline data. library(tidyverse); library(skimr); Support.Times <- structure(list(Screened = c(26.9, 28.4, 23.9, 21.8, 22.4, 25.9, 26.5, 20, 23.7, 23.7, 22.6, 19.4, 27.3, 25.3, 27.7, 25.3, 28.4, 24.2, 20.4, 29.6, 27, 23.6, 18.3, 28.1, 20.5, 24.1, 27.2, 26.4, 24.5, 25.6, 17.9, 23.5, 25.3, 20.2, 26.3, 27.9), Not.Screened = c(24.7, 19.1, 21, 17.8, 22.8, 24.4, 17.9, 20.5, 20, 26.2, 14.5, 22.4, 21.1, 24.3, 22, 24.3, 23.

Tables, Pivots, Bars, and Mosaics

R Markdown There is detailed help for all that Markdown can do under Help in the RStudio. The key to it is knitting documents with the Knit button in the RStudio. If we use helpers like the R Commander, Radiant, or esquisse, we will need the R code implanted in the Markdown document in particular ways. I will use Markdown for everything. I even use a close relation of Markdown in my scholarly pursuits.
