There are many ways for Data visualization in R, Lattice graphics is one of the way to plot graphics in R, and look different from standard R graphics.

In this task, I encourage you to make simple visualization

• create a simple data set with 4 different variable (W,X,Y,Z) where W,X,Y are numeric and Z is character with different group character (a, b ,c)
• show your data frame
• plot a scatter plot -make a plot from data shown above in two different panels, split by variable z -Make two data series on the same plot.

Good luck!
