The process for defining the dimensions of a plot in R while using the rpy2 module in Python on a Google Colab document involves the following steps:

1. Import the necessary modules:

import rpy2
from rpy2.robjects import r

1. Define the dimensions of the plot using R code:

r("options(repr.plot.width=6, repr.plot.height=4)")

This code sets the width of the plot to 6 inches and the height to 4 inches.

1. Plot the data using R code:

r("plot(x, y)")

In this example, the plot function is used to plot two variables x and y.

The full code would look something like this:

import rpy2
from rpy2.robjects import r

# Set plot dimensions
r("options(repr.plot.width=6, repr.plot.height=4)")

# Define data to plot
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]

# Plot the data
r("plot(x, y)")

In this example, the plot will be 6 inches wide and 4 inches tall. The plot function will be used to plot the data contained in the x and y variables.
