Recipe Objective

How to create a contour plot using a lattice package in R?

Contour plots are the top view of a surface that is 3-dimensional in nature and converted into 2-dimensional charts. Lattice is a data visualization and graphics package in R - graph_type (formula, data) This recipe demonstrates an example of contour plot plots.

Step 1 - Install necessary package and library

install.packages("lattice") library(lattice)

Step 2 - Define the data

data <- dimnames(volcano) # using the "volcano" dataset

Step 3 - Using contour()

Syntax - contour(x,xlab,ylab) where, x - input data xlab - label for X axis ylab - label for Y axis

contour(x=volcano, xlab = "Row", ylab = "Column") # Contour plot for volcano dataset {"mode":"full","isActive":false}
