Lattice绘图

lattice包提供了用于可视化单变量和多变量数据的一整套图形系统。许多用户转向使用lattice包是因为它能很容易地生成网格图形。网格图形能够展示变量的分布或变量之间的关系。

例：
data(mtcars)
attach(mtcars)

# Create factors with value labels
gear <- factor(gear, levels=c(3, 4, 5),
              
labels=c("3 gears", "4 gears", "5 gears"))

cyl <- factor(cyl, levels=c(4, 6, 8),
             
labels=c("4 cylinders", "6 cylinders", "8 cylinders"))

# Generate plots
densityplot(~ mpg,
           
main="Density Plot",
           
xlab="Miles per Gallon")

densityplot(~ mpg | cyl,
           
main="Density Plot by Number of Cylinders",
           
xlab="Miles per Gallon")

bwplot(cyl ~ mpg | gear,
      
main="Box Plots by Cylinders and Gears",
      
xlab="Miles per Gallon", ylab="Cylinders")

xyplot(mpg ~ wt | cyl * gear,
      
main="Scatter Plots by Cylinders and Gears",
      
xlab="Car Weight", ylab="Miles per Gallon")

cloud(mpg ~ wt * qsec | cyl,
     
main="3D Scatter Plots by Cylinders")

dotplot(cyl ~ mpg | gear,
       
main="Dot Plots by Number of Gears and Cylinders",
       
xlab="Miles Per Gallon")

splom(mtcars[c(1, 3, 4, 5, 6)],
     
main="Scatter Plot Matrix for mtcars Data")

detach(mtcars)
