Variable Penalty Dynamic Time Warping for aligning GC-MS chromatograms to a master signal and more. With the appropriate penalty this method performs good alignment without altering the shape of peaks in chromatography data.

## Installation

VPdtw can be installed from CRAN:

```

install.packages("VPdtw")

```

Alternatively, the development version can be installed from GitHub:

```R

install.packages("remotes")

remotes::install_github("ethanbass/VPdtw")

```

or from R Universe:

```

install.packages("chromConverter", repos="https://ethanbass.r-universe.dev/")

```
