The covid19sf package provides a daily summary of the covid19 cases in San Francisco. The package includes the following datasets:
covid19sf_geo - Confirmed cases and deaths summarized
by geographycovid19sf_hospital - Hospital capacity datacovid19sf_hospitalizations - Hospitalizations datacovid19sf_housing - Alternative housing sitescovid19sf_test_loc - Testing locationscovid19sf_tests - Daily number of testscovid19sf_vaccine_demo - Summary of vaccine doses given
to San Franciscans by demographics groups (age and race)covid19sf_vaccine_demo_ts - Time series view of vaccine
doses given to San Franciscans by demographics groups (age and
race)covid19sf_vaccine_geo - COVID-19 vaccines given to San
Franciscans by geographycovid19sf_population - COVID-19 cases by population
characteristics over timeThe following dataset were deprecated and replaced by the
covid19sf_population dataset:
covid19sf_demo- Cases summarized by date, transmission
and case dispositioncovid19sf_homeless - Confirmed cases by
homelessnesscovid19sf_age - Cases summarized by age groupcovid19sf_gender - Confirmed cases summarized by
gendercovid19sf_summary - Cases summarized by date,
transmission and case dispositionData soucre: San Francisco, Department of Public Health - Population Health Division through the San Francisco Opne Data protal website
# install.packages("devtools")
devtools::install_github("RamiKrispin/covid19sf")The ccovid19sf package provides different views for the covid19 cases in San Francisco. That includes case distribution by age, gender, race, etc. The following examples demonstrate some of the data use cases.
library(covid19sf)The covid19sf_population provides a daily summary of new
and cumulative positive cases by the following demograpich groups:
data(covid19sf_population)
head(covid19sf_population)

characteristic_type variable to filter the data:

df_age <- covid19sf_population %>%
filter(characteristic_type == "Age Group")

age_order <- df_age %>%
select(characteristic_group, characteristic_group_sort_order) %>%
distinct() %>%
arrange(characteristic_group_sort_order)
df_age$characteristic_group <- factor(df_age$characteristic_group, levels = age_order$characteristic_group)The following box-plot shows the distribution of the positive cases by age group:
library(plotly)
plot_ly(df_age,
color = ~ characteristic_group,
y = ~ new_cases,
boxpoints = "all",
jitter = 0.3,
pointpos = -1.8,
type = "box" ) %>%
layout(title = "Distribution of Daily New COVID-19 Cases in San Francisco by Age Group",
yaxis = list(title = "Number of Cases"),
xaxis = list(title = "Source: San Francisco Department of Public Health"),
legend = list(x = 0.9, y = 0.9),
margin = list(t = 60, b = 60, l = 60, r = 60))
Here is the overall distribution of cases by age group as of 2021-12-11:
df_age %>%
filter(specimen_collection_date == max(specimen_collection_date)) %>%
plot_ly(values = ~ cumulative_cases,
labels = ~ characteristic_group,
type = "pie",
textposition = 'inside',
textinfo = 'label+percent',
insidetextfont = list(color = '#FFFFFF'),
hoverinfo = 'text',
text = ~paste(" Age Group:", characteristic_group, "<br>",
"Total:", cumulative_cases, "<br>",
"Population Estimation:", population_estimate,
paste("(",round(100* cumulative_cases/population_estimate, 1) ,"%)", sep = ""))) %>%
layout(title = ~ paste("Total Cases Dist. by Age Group as of", max(specimen_collection_date)),
margin = list(t = 60, b = 20, l = 30, r = 60))
The package provides several geo-spatial dataset:
covid19sf_vaccine_geo - COVID-19 vaccines given to San
Franciscans by geographycovid19sf_geo - Confirmed cases and deaths summarized
by geographycovid19sf_test_loc - Testing locationsThose three datasets are sf objects, ready to use. For
example, plotting the COVID19 vaccination data by geography:
library(sf)

df <- covid19sf_vaccine_geo %>% filter(area_type == "Analysis Neighborhood") %>%
dplyr::mutate(perc_complated = percent_pop_series_completed * 100)We will plot the object Using the sf package:
plot(df[, c("perc_complated", "geometry")],
main = "San Francisco - Percentage of Fully Vaccinated Population by Geo",
key.pos = 1, axes = TRUE, key.width = lcm(1.2), key.length = 1.0)
