R: Data Analysis and Visualization

Zooming and filtering

Sometimes, we need to zoom in to see the special pattern in the dataset. In this recipe, we will see how we can zoom in to the plot with the use of a simple argument in the existing function.

Getting ready

Let's recall the same data with continuous variables only (con_dat). We want to create the plot with 20 to 50 percent of the data based on sorted variables.

How to do it...

The code to produce the plot by zooming into the mpg variable with 20 to 50 percent of the observation is as follows:

tableplot(con_dat,from=20,to=50,sortCol=mpg)

How it works…

The from and to arguments specify which part of the data needs to be used during plotting. ...
