Creating a Histogram Using RStudio

Creating a Histogram Using RStudio

These instructions assume that you’ve already installed the necessary package and that you’ve imported and attached your data file. 

To create a histogram in RStudio, you will invoke the following command: 

hist(data,main,xlab,ylab,xlim,ylim,col,border,breaks=?)

  • Data = variable x
  • Main = title 
  • Xlab = x label
  • Ylab = y label
  • Xlim = x limit
  • Ylim = y limit
  • Col = color of bars
  • Border = color of bar borders
  • Breaks = bucket or column width

Here’s an example of a histogram being created from the data set for the variable TestGrades.  The title of the histogram is test grades, the x label is grades, the y label is total, the column color is set to blue with a yellow border.  Finally, the bucket width (column width) has been set to 10

hist(TestGrades,main="test grades",xlab="grades", ylab="total", col="blue", border="yellow", breaks=10)
