How to add grids to plots in R
The plot function in Base R does not automatically put up a grid. For example, if you do a simple plot like this,
# Plot y = square(x) for x between 1 and 10 > plot(1:10,(1:10)^2)
It is pretty hard to figure out where exactly each of these points lie. A grid would be nice to quickly get the x and y values.
# nx stands for the number of vertical lines on the x-axis. # ny = nx is a default argument > grid( nx= 10 )
The default grid lines are grey in color. You can change it by specifying the col argument.
> grid( nx = 10, col = "lightblue")
