# R-packages

A considerable amount of software grew out of my research. Most of this code is made available as packages for the freely available software R and can be downloaded from CRAN. The packages were first uploaded to CRAN in the years indicated.

While working at the Division of Biostatistics at the University of Zurich I maintained another R package, biostatUZH, which is not publicly available. This package collected all functions that were developed at the department at that time.

At Roche I developed three additional packages that collect functions in context of clinical and diagnostic studies and are used by colleagues within Roche.

# Packages under development but current version publicly available

# Contributions to R-packages

The methodology introduced in Rufibach, K. (2012), *A smooth ROC curve estimator based on log-concave density estimates*
is also available in the function smooth() in the R package pROC .

# Further software

Below you find some R code that has not (yet) made it into a proper R package.
