Accessible geospatial socio-economic metrics

I gave an invited talk at the National Cancer Institute Division of Cancer Prevention Multi-Cancer Detection Working Group entitled “Accessible geospatial socio-economic metrics.” The talk was an introduction to my open-source R package in the Comprehensive R Archive Network (CRAN) named ndi that I developed as a postdoctoral Cancer Prevention Fellow.

New CRAN Package {ndi}

My fourth R package is published in the Comprehensive R Archive Network named ndi. It computes various geospatial neighborhood deprivation indices (NDI) and other metrics of social vulnerability in the United States.

Plotting a Neighborhood Network with ggplot2

Here is an example of plotting a neighborhoods network with ggplot2 using the sf and sfdep packages for counties in a U.S. state. We can display the “weights” feature of the neighborhoods network as the size of the line segments by scaling the size aesthetic with + scale_size_identity().

New CRAN Package {envi}

My third R package is published in the Comprehensive R Archive Network named envi. It estimates the ecological niche using presence/absence data and the spatial relative risk function via the sparr package.

New CRAN Package {gateR}

My second R package is published in the Comprehensive R Archive Network named gateR. It estimates clustering of cytometry cells using markers and the spatial relative risk function via the sparr package.

Creating a hexsticker for the {sparrpowR} package

I present code to create the hexsticker for the sparrpowR package using the hexSticker and spatstat packages. The sparrpowR calculated the statistical power for a spatial relative risk function from the sparr package.

New CRAN Package {sparrpowR}

My first R package is in the Comprehensive R Archive Network named sparrpowR. It provides a statistical power calculation for the spatial relative risk function via the sparr package. See the public Github repository for more details.

Animating Spatio-Temporal COVID-19 Data

I present an update to my previous posts #1 and #2. This update can also be found on a public GitHub repository. Starting May 17, 2020 the DC Mayoral Office began releasing testing information by neighborhood on their coronavirus data portal.

DCEG Informatics Tool Challenge Award

I received an Informatics Tool Challenge Award from the NCI Division of Cancer Epidemiology and Genetics for a project entitled “sparrpowR: A flexible R package and webtool to estimate statistical power of a spatial cluster detection technique.

Cluster Detection in PCoA Space using Kernel Density Estimation

I present code to identify relative spatial clustering in multidimensional scaling / principal coordinate analysis (MDS/PCoA) space. I use a spatial relative risk function risk from the sparr package.
