gtrellis: an R/Bioconductor package for making genome-level Trellis graphics.

Area of Science:

• Genomics
• Bioinformatics
• Data Visualization

Background:

• Trellis graphics are a visualization technique that partitions data by categorical variables into a grid of panels.
• Widely applied in genomic data analysis for parallel statistical comparisons and revealing multivariate relationships.
• Existing software lacks genomic-specific functionality for effective Trellis graphic generation.

Purpose of the Study:

• Introduce the gtrellis package for efficient and extensible genomic data visualization.
• Provide flexible Trellis layouts for optimal arrangement of genomic categories.
• Enable multi-track visualization for parallel analysis of genomic data properties.

Main Methods:

• Development of the gtrellis R package.
• Implementation of flexible Trellis layout capabilities.
• Inclusion of multi-track visualization features.
• Design of an extensible framework for user-defined graphics.

Main Results:

• gtrellis enables efficient visualization of genomic data in a Trellis layout.
• Highly flexible layouts facilitate effective arrangement of genomic categories.
• Supports multiple parallel tracks for visualizing diverse genomic data properties.
• Offers an extensible framework for incorporating custom graphics.

Conclusions:

• gtrellis provides an effective method for visualizing genomic data and high-dimensional relationships genome-wide.
• The package's flexibility allows adaptation for specialized purposes.
• Facilitates novel visualizations, potentially leading to the discovery of new genomic patterns.
