Overview

The CamelRatiosIndex package includes a fully interactive Shiny dashboard that provides a graphical interface for computing and exploring CAMEL indices. The dashboard is ideal for:

  • Regulators who need quick visual summaries without writing code
  • Students learning about the CAMEL framework
  • Presentations where live computation adds impact
  • Exploratory analysis before formal reporting

Launching the Dashboard 

library(CamelRatiosIndex)

# Launch with default settings
launch_dashboard()

# Launch on a specific port (useful for servers)
launch_dashboard(port = 3838, host = "0.0.0.0")

  • Top/bottom performers: Quick summary tables
  • Download buttons: Export results as CSV, Excel, or RDS Results

4. Visualisations

  • Line plot: Percentage differences across all banks with highlighting
  • Bar chart: Horizontal comparison with colour-coded performance
  • Radar chart: CAMEL weight distribution (base year)
  • Histogram: Distribution of performance differences
  • Lollipop chart: Bank ranking relative to base year Visuals from Results

5. Factor Analysis

  • Eigenvalue plots: Scree plots for base and current years
  • Communality weights: Bar chart comparing base vs current weights
  • Weights table: Numerical comparison with differences
  • Factor loadings table: Full loading matrix from base year Factor Analysis Visuals

6. Data Explorer

  • Raw base year data
  • Raw current year data
  • Relativity ratios (current/base)
  • Laspeyres and Paasche intermediate indices Explore Results DataMore Exploration

7. About

  • Package information
  • Methodology summary
  • Citation information

Data Upload Format

The dashboard accepts CSV files with this exact structure:

Column Name Description
1 Bank Bank identifier (character)
2 Ca Capital Adequacy ratio
3 Aq Asset Quality ratio
4 Me Management Efficiency ratio
5 Eq Earnings ratio
6 Lm Liquidity ratio

The dashboard automatically inverts Aq, Me, and Lm (higher = worse performance).
