R – lattice Packages
The lattice package uses grid package to provide better relationships between the data. It is an add-on package for the implementation of Trellis graphics (graphics that shows relationships between variables conditioned together).
To install Lattice Packages in R
install.packages("lattice")
There are so many graphs present in the package such as barchart, counterplot, densityplot, histogram, etc. A simple format to use is:
graph_type(formula, data)
where,
- graph_type represents the type of graph to represent
- formula specifies the variables or conditioned variables
To know about all functions of package:
library(help = "lattice")
Below is an implementation of some of the graphical functions in lattice package.
Example 1:
R
library(lattice)attach(mtcars)# Output to be present as PNG filepng("DensityPlotLatticeGFG.png")# Create Density Plot for HPdensityplot(~hp, main ="Density plot of HP", xlab ="HP")# Saving the filedev.off() |
Output:
Example 2:
R
library(ToothGrowth)# Output to be present as PNG filepng("HistogramLatticeGFG.png")# Using ToothGrowth dataset# To Create Histogram of lengthhistogram(~len, data = ToothGrowth,main = "Histogram of Length")# Saving the filedev.off() |
Output:
Grid and Lattice Packages in R Programming
Every programming language has packages to implement different functions. Many functions are bundled together in a package. To use those functions, installation and loading of these packages are required. In R programming, there are 10, 000 packages in the CRAN repository. Grid and Lattice are some of the packages in R Programming Language which implement graphical functions to develop some graphical outputs such as rectangle, circle, histogram, barplot, etc.
