Plotting of Data using Generic plots in R Programming – plot() Function

plot() function in R Programming Language is defined as a generic function for plotting. It can be used to create basic graphs of a different type.

Syntax: plot(x, y, type)

Parameters

• x and y: coordinates of points to plot
• type: the type of graph to create

Returns: different type of plots

Plotting Data in R Programming Language

Example 1: Draw Points using plot() Function in R 

R

plot(3, 4)

Output:

Example 2: Draw Multiple Points

R

plot(c(1, 3, 4), c(4, 5 , 8))

Output:

Example 3: Sequences of Points

R

plot(1:20)

Output:

Example 4:  R program to plot a graph

R

# Values for x and y axis
x <- 1:5; y = x * x

# Using plot() function
plot(x, y, type = "l")
plot(x, y, type = "h")

Output:

In the above example type=“l” stands for lines graph, type=“h” stands for ‘histogram’ like vertical lines.

Example 5: R program to plot a different graph

R

# R program to plot a graph

# Creating x and y-values
x - 1:5; y = x * x

# Using plot function
plot(x, y, type = "b")
plot(x, y, type = "s")
plot(x, y, type = "p")

Output:

Here, in the above example type=“b” stands for both that means points are connected by a line

type=“s”indicates stair steps

type=“p” for points (by default).
