Suppose we have a dataset called "house_prices" which lists the selling prices in various suburbs (given in 1000's of dollars), in a column called PRICE. The following is a command which adds a new column called CAPPED_PRICE to the dataset:

house_prices$CAPPED_PRICE <- with(house_prices, ifelse(PRICE > 600, 600, PRICE))

Describe what what you think this command does.
