shinyExprPortal is a configurable Shiny portal for the visual exploration and analysis showcase of molecular expression data and phenotype data, such as observed clinical measures. The package is designed for deploying portals using a text-based configuration file with minimal programming. The portal includes modules for exploring correlations between expression and measures, visualizing the results of differential expression analysis and showcasing results of other downstream analysis methods such as pathways and correlated networks. The interface is designed for gene expression, but the computational methods are compatible with any matrix with samples in columns and entities, such as proteins, in rows.
For initial exploration, any expression matrix containing abundance or counts and data frames containing observed measures can be loaded in. For differential expression and other methods, the package is compatible with the outputs of packages such as limma and WCGNA. The correlation modules can be used early in the lifecycle of a bioinformatics project, while the other modules can be added as new downstream analysis results are produced. The use of the configuration file also means that the portal can be easily versioned.
A demo of the portal is available here.
The package relies on other packages from CRAN and Bioconductor. To ensure the installation goes smoothly, install BiocManager by running:
install.packages("BiocManager)You can then install the latest version of the package using:
install.packages("shinyExprPortal")Alternatively, you can install the current development version using devtools (installing devtools first if necessary):
install.packages("devtools")
devtools::install_github("C4TB/shinyExprPortal", dependencies = TRUE)If you only have one set of set of samples for a group of subjects,
i.e. one sample per patient, you can check vignette("shinyExprPortal")
for a quick start guide to set up the configuration file.
If your subjects have one more samples, e.g. collected over time or
from different tissues, you should check the data preparation guide in
vignette("dataprep")
and the full configuration guide vignette("config")
Once you have completed either of the steps above, you can open and run the app.R file created to test the portal.
The full configuration guide in vignette("config")
describes all the dependencies, file requirements, mandatory and
optional settings for each of the modules currently supported by the
package.
vignette("customization")
describes how to customize the visual style of the portal and how to add
new functionality through programming new modules. The package supports
customization via the configuration file at a global level using bslib. Some modules
also support the customization of the colors used in the
visualizations.
The package is also compatible with new modules that can be added without modifying the source code of the portal or the package. New functionality can be developed and tested without having to clone the repository or recompile the package. We are also open for suggestions of new modules, please use the GitHub issues page for that.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
