The ospsuite package is compatible with R version 4.x.x and can be used on Windows and Linux (Ubuntu) operating systems.

ospsuite is not available on CRAN and also depends on packages from the OSP ecosystem that are not available on CRAN. Please follow the instructions below to install the packages and all required dependencies.

As {ospsuite} relies on {rSharp}, install its external dependencies (Visual C++ Redistributable and .NET 8) by following these instructions:

• For Windows
• For Linux

The latest released version of the package can be installed from GitHub using the {remotes} package. The code below will download and install all the required dependencies.

install.packages("remotes")
remotes::install_github("Open-Systems-Pharmacology/OSPSuite-R@*release")

Get the latest development version with:

install.packages("remotes")
remotes::install_github("Open-Systems-Pharmacology/OSPSuite-R")

It is also possible to install manually from archive pre-built archive files provided with the release.

When installing from such files, the CRAN dependencies need to be installed manually first.

# Install dependencies (e.g. R6) which are on CRAN
install.packages("data.table")
install.packages("dplyr")
install.packages("ggplot2")
install.packages("ggtext")
install.packages("jsonlite")
install.packages("lifecycle")
install.packages("openxlsx")
install.packages("patchwork")
install.packages("purrr")
install.packages("R6")
install.packages("readr")
install.packages("rlang")
install.packages("stringr")
install.packages("tidyr")
install.packages("xml2")

Each of the pre-built released packages are available as a a binary *.zip. OSPSuite-R binary archive can be downloaded from here. The other non-CRAN dependencies needed for OSPSuite-R also have to be downloaded and manually installed:

• {rSharp}
• {ospuite.utils}
• {tlf}

If you use RStudio IDE, you can use the Install option in the Packages pane and select the option Install from -> Package Archive File to install a package from binary *.zip files.

NB: The CRAN dependencies of {rSharp}, {ospuite.utils} and {tlf} were already installed during the previous step.

# Install `{rSharp}` from local file 
# (`pathTo_rSharp.zip` here should be replaced with the actual path to the `.zip` file)
install.packages(pathTo_rSharp.zip, repos = NULL)

# Install `{ospsuite.utils}` from local file
# (`pathTo_ospsuite.utils.zip` here should be replaced with the actual path to the `.zip` file)
install.packages(pathTo_ospsuite.utils.zip, repos = NULL)

# Install `{tlf}` from local file
# (`pathTo_tlf.zip` here should be replaced with the actual path to the `.zip` file)
install.packages(pathTo_tlf.zip, repos = NULL)

# Install `{ospsuite}` from local file
# (`pathToOSPSuite.zip` here should be replaced with the actual path to the `.zip` file)
install.packages(pathTo_OSPSuite.zip, repos = NULL)

• On Windows, set Settings > Language > Administrative language settings > Current language for non-Unicode programs to English (United States) and reboot.

• On Linux, set the environment variable LC_ALL before starting R:

  export LC_ALL=en_US.UTF-8

The ospsuite package uses the features implemented in PK-Sim and MoBi by creating .NET objects (e.g. a simulation) and using them from R. These objects cannot be saved as part of the workspace and reloaded on next start. Upon restoring the workspace, the objects will be NULL and cannot be re-used.

The {ospsuite} package requires some shared libraries to get access to PK-Sim functionality. To get the latest libraries(.dll on Windows or .so on Linux), run the script file update_core_files.R provided with this package.

Since {ospsuite} contains this binary files, it is considered as a binary package and thus cannot be submitted to CRAN in this state.

The package follows the versioning process described in the OSP R collaboration guide.

For development version, each time a pull request is merged, this github action automatically bumps the .9000 version suffix by one.

Everyone interacting in the Open Systems Pharmacology community (codebases, issue trackers, chat rooms, mailing lists etc.) is expected to follow the Open Systems Pharmacology code of conduct.

We encourage contribution to the Open Systems Pharmacology community. Before getting started please read the contribution guidelines. If you are contributing to the codebase, please be familiar with the R coding standards as well as the collaboration guide.
