Extremely useful approach for graphical exploratory data analysis (EDA). Allows to examine for complicated, multiple variable relationships. Types of plots:
• xyplot: scatterplot
• bwplot: boxplots
• stripplot: display univariate data against a numerical variable
• dotplot: similar to stripplot
• histogram
• densityplot: kernel density estimates
• barchart
• piechart: (Not available in R)
• splom: scatterplot matrices
• contourplot: contour plot of a surface on a regular grid
• levelplot: pseudo-colour plot of a surface on a rectangular grid
• wireframe: perspective plot of a surface evaluated on a regular grid
• cloud: perspective plot of a cloud of points (3D scatterplot)
