# vlad
An R-package which contains functions to set up risk-adjusted quality control charts in health care.
## Main features
- Risk-adjusted CUSUM chart control limit calculations based on fast and accurate Markov chain approximations [@Knoth.etal_2019]
- Risk-adjusted CUSUM chart based on E-O [@Wittenberg.etal_2018]
- Risk-adjusted CUSUM chart based on log-likelihood ratio statistic [@Steiner.etal_2000]
- Algorithms are implemented using Rcpp, RcppArmadillo and parallel computation
## Installation
You can install the released version of **vlad** from
[CRAN](https://CRAN.R-project.org/package=vlad) with:
``` r
install.packages("vlad")
```
You can install the development version from [GitHub](https://github.com/wittenberg/vlad) with:
``` r
# install.packages("devtools")
devtools::install_github("wittenberg/vlad")
```
The package compiles C++ source code during installation, therefore you need the appropriate compilers:
On _Windows_ you need [Rtools](https://cran.r-project.org/bin/windows/Rtools/) available from CRAN.
On _macOS_ you need the Clang 6.x compiler and the GNU Fortran compiler from [macOS tools](https://cran.r-project.org/bin/macosx/tools/).
Having installed the compilers, you need to open a terminal and start R via 'PATH=/usr/local/clang6/bin:$PATH R'.
You can then install the package via *devtools::install_github("wittenberg/vlad")*
