# Minimize memory usage for resource-constrained environments
basegraphics(
  data = mydata,
  plot_type = "histogram",
  x_var = "Age",
  bins = 10,            # Fewer bins = less memory
  color_scheme = "default",  # Simple colors
  add_grid = FALSE,
  show_statistics = FALSE
)

  • Choose appropriate point sizes for data density
  • Enable grid lines for easier reading

2. Color Strategy

  • Use distinct colors for groups (rainbow, heat)
  • Consider colorblind-friendly palettes
  • Limit to 6-8 groups for clarity

3. Statistical Enhancement

  • Enable statistics for insight generation
  • Add regression lines for trend analysis
  • Show sample sizes for group comparisons

4. Performance Optimization

  • Sample large datasets for interactive exploration
  • Use simpler colors and smaller points for big data
  • Disable unnecessary features for speed

Troubleshooting

Common Issues and Solutions

No Plot Appears

Problem: Plot window is empty Solutions: - Verify x_var is specified - Check that variables exist in data - Ensure data has complete cases for selected variables

Colors Not Showing

Problem: All points appear same color despite group_var Solutions: - Confirm group_var is factor or character - Check that group_var has multiple levels - Try different color_scheme options

Statistics Not Displaying

Problem: show_statistics = TRUE but no statistics appear Solutions: - Verify appropriate plot type (not all support statistics) - Check for sufficient data (need >1 observation) - Ensure variables are numeric for correlation

Pairs/Matrix Plots Empty

Problem: Pairs or matrix plots show error message Solutions: - Ensure dataset has at least 2 numeric variables - Check for adequate sample size (n > 2) - Remove variables with all missing values

Custom Limits Not Working

Problem: Axis limits don’t change despite custom_limits = TRUE Solutions: - Verify custom_limits = TRUE - Ensure x_min < x_max and y_min < y_max - Check that limits are reasonable for your data range

Performance Issues

Problem: Slow plotting with large datasets Solutions: - Sample data for exploration: data[sample(nrow(data), 1000), ] - Use smaller point sizes - Disable grid and statistics for speed - Consider simpler color schemes
