Overview

About

Maintained by Simon ManthaCRAN page ↗GitHub ↗Website ↗

Streamlined annotation pipeline for collection and aggregation of time-to-event data in retrospective clinical studies. 'CEDARS' aims to systematize and accelerate the review of electronic health record (EHR) corpora. It accomplishes those goals by deploying natural language processing as a tool to assist detection and characterization of clinical events by human abstractors. The online user manual presents the necessary steps to install 'CEDARS', process EHR corpora and obtain clinical event dates: https://cedars.io.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/CEDARS/CEDARS_1.90.tar.gz"
pkgFile <- "CEDARS_1.90.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.90) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("simon-hans/CEDARS")

Development version from simon-hans/CEDARS. Installs pak first if it is not already available.
