How to plot excel data in R?

Plotting graph in R using an excel file, we need an excel file with two-column in it, the values in the first column will be considered as the points at the x-axis and the values in the second column will be considered as the points at the y-axis. In this article, we will be discussing the approach to plot a graph using an excel file in R language.

To import and read the excel file to the R console, the  read_excel() function from readxl library in R will be used. This function will read an excel-file available in your current working directory. To install the package of the readxl library in R the user must need to follow the following syntax in the R console.

Syntax:

install.packages("readxl") 

Data in use:

plot() function is used for plotting of R objects. With the provided parameters this function returns a scatter plot by default.

Syntax:

plot(x,y,main,xlab,ylab,sub,asp)

Parameters:

• x:-the x coordinates of points in the plot
• y:-the y coordinates of points in the plot
• main:-an overall title for the plot
• sub:-a subtitle for the plot
• xlab:-a title for the x-axis
• ylab:-a title for the y-axis
• asp:-the y/x aspect ratio

Return:

Scatter plot of the given x and y values.

Approach

• Import library
• Import excel file
• Read its data
• Plot graph
• Display plot

Example:

library(readxl)

Data_gfg <- read_excel("Data_gfg.xlsx")

plot(x = Data_gfg$x,y = Data_gfg$y,
     xlab = "x-axis",
     ylab = "y-axis",
     main = "Plot"
)
