Coxmos is still a beta-version. Work in progress. We strongly recommend to not use it yet.
The Coxmos R package is an end-to-end pipeline designed for the study of survival analysis for high dimensional data. Updating classical methods and adding new ones based on sPLS technologies. Furthermore, includes multiblock functions to work with multiple sets of information to improve survival accuracy.
The pipeline includes three basic analysis blocks:
Computing cross-validation functions and getting the models.
Evaluating all the models to select the better one for multiple metrics.
Understanding the results in terms of the global model and the original variables.
Coxmos contains the necessary functions and documentation to obtain from raw data the final models after compare them, evaluate with test data, study the performance individually and in terms of components and graph all the results to understand which variables are more relevant for each case of study.
Some of the metrics available in Coxmos are optional based and will not be included in the standard Coxmos installation. A list of all optional packages are shown below:
The Coxmos R package and all the remaining dependencies can be installed from GitHub using devtools:
devtools::install_github("BiostatOmics/Coxmos")To access vignettes, you will need to force building with devtools::install_github(build_vignettes = TRUE). Please note that this will also install all suggested packages required for vignette build and might increase install time. Alternatively, an HTML version of the vignette is available under the vignettes folder.
In order to use Coxmos, you will need the following items:
Please note that two toy datasets are included in the package. Details to load and use them can be found in the package’s vignette.
If you encounter a problem, please open an issue via GitHub.
