Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

5.6K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Interpreting R Charts01:22

Interpreting R Charts

99
R chart, or range chart, is a fundamental tool in statistical process control used to monitor the variability within a process. It complements the X-bar (x̄) chart by focusing on the range of the data, rather than individual values, providing a clear picture of the process dispersion over time.
An R chart plots the range of subsets of measurements collected from a process. Each point on the chart represents the range—defined as the difference between the maximum and minimum...

Area of Science:

  • Medical Informatics
  • Data Visualization
  • Computational Biology

Background:

  • Body maps are crucial for documenting pain location and extent.
  • Increasing electronic body map data necessitates advanced visualization tools for clinical and research use.
  • Existing tools may lack the flexibility for individual and mass-scale data analysis.

Purpose of the Study:

  • To introduce CHOIRBM, an R package and web application for analyzing and visualizing patient body map data.
  • To provide clinic- and research-ready tools for both individual and large-scale body map data.
  • To leverage the grammar of graphics system for extensible and modular data visualization.

Main Methods:

  • Development of CHOIRBM as an R package utilizing the ggplot2 graphics system.
  • Implementation of functions for analyzing and plotting patient body map data from the CHOIR Body Map (CBM).
  • Creation of a companion web application for enhanced accessibility and usability.

Main Results:

  • CHOIRBM offers simplified analysis and plotting of CBM data at individual and large-dataset levels.
  • The package is modular and extensible, built upon the widely-used ggplot2.
  • Example analyses demonstrate the package's functionality and utility in clinical and research settings.

Conclusions:

  • CHOIRBM provides an efficient solution for visualizing patient body map data.
  • The R package and web application support both clinical practice and research endeavors.
  • Its open-source nature and foundation on ggplot2 ensure future development and community contributions.
