Software

I have developed and published several R packages and tools.

A subset of the packages I have published are listed here in alphabetical order. Click the link to get a summary of the tool and links to the software and more details.

cpr

Control Polygon Reduction

Description

Implementation of the Control Polygon Reduction and Control Net Reduction methods for finding parsimonious B-spline regression models.

ensr

Elastic Net Searcher

Description

Elastic net regression models are controlled by two parameters, lambda, a measure of shrinkage, and alpha, a metric defining the model’s location on the spectrum between ridge and lasso regression. glmnet provides tools for selecting lambda via cross validation but no automated methods for selection of alpha. Elastic Net SearcheR automates the simultaneous selection of both lambda and alpha. Developed, in part, with support by NICHD R03 HD094912.

pccc

Pediatric Complex Chronic Conditions

Description

An implementation of the pediatric complex chronic conditions (CCC) classification system using R and C++.

pedbp

Pediatric Blood Pressure Percentiles and Growth Charts

Description

Data and utilities for estimating pediatric blood pressure percentiles by sex, age, and optionally height (stature). Additionally, CDC and WHO growth charts have been implemented for things such as weight for age, weight for stature, stature for age, and others.

phoenix

Phoenix Sepsis and Septic Shock Criteria

Description

The phoenix R package and Python module implement the Phoenix criteria for pediatric sepsis and septic shock.

qwraps2

Quick Wraps 2

Description

A collection of tools I use for building summary tables, graphics, and general formating of reproducible reports.

REDCapExporter

REDCap Exporter

Description

A set of tools to download data and meta data from REDCap projects via the REDCap API. The metadata is used to format the records into a nearly analysis ready data set.
