PAVER allows for summary interpretation and visualization of pathway analyses.
PAVER is designed to work with the output of pathway analysis tools. The package includes a vignette with an example dataset that explains it’s functionality. The R Shiny application for the PAVER R package is hosted at https://cdrl.shinyapps.io/PAVER/. For more detailed information on PAVER and its functionalities, please read further below and also refer to the article on the Cognitive Disorders Research Laboratory (CDRL) website here.
You may download the latest source release for PAVER here. You may also download the latest release of the R Shiny app for the PAVER R package here.
Pre-computed pathway embeddings for use with PAVER are available for download here.
You can install the development version of PAVER from GitHub with:
if (!requireNamespace("remotes", quietly = TRUE))
install.packages("remotes")
remotes::install_github("willgryan/PAVER")PAVER offers different visualizations for exploring and interpreting pathway clusters.
The theme plot is a scatter plot showing all pathways in the dataset,
colored by theme. The theme plot is useful for identifying pathways that
are similar to each other, and for identifying pathways that are
outliers. The theme plot can be generated using the PAVER_theme_plot
function.
The heatmap plot shows the enrichment scores for each pathway in each
cluster. The heatmap plot is useful for quantitatively identifying
identifying differences in pathway regulation across different pathway
analyses. The heatmap plot can be generated using the
PAVER_hunter_plot function.
