Formatting Your Histogram

Sometimes we have to change things because R's default setting isn't suitable for our graph. In the same way as we added a title argument to hist(), we can change the scale of the y-axis through adding the argument ylim followed by the range we want (e.g. for a scale from 0 to 50, we would say ylim = c(0,50)). We can also label the x-axis using the argument xlab = "title", or change the colour of the bars to blue with the argument col = "blue".

Instructions

100 XP
  • Change the y axis scale from 0 to 20
  • Make the bars "red"
  • Label the x-axis "Number of Carburetors"
  • Remember that you should separate each argument with a comma
