my question is , if i want to create a boxplot from renovation house only .what should i do
thank.
ps. sorry for my poor English skill. If you have another question about this you can ask me below here.
thanks again.

Since this is homework, I will not answer completely but I will suggest a direction. Do you know how to make a new data frame that includes only the rows where renovation == "yes"? Your instructor might have called this "making a subset of a data frame".
