Practicing syntax with grep

You have just completed an ice-breaker exercise at work and you recorded 10 facts about your boss. You saved these 10 facts into a vector named text. Using regular expressions, you want to summarize your bosses' responses.

A few notes on regular expressions in R:

When using grep(), setting value = TRUE will print the text instead of the indices.
You can combine patterns such as a digit, "\\d", followed by a period "\\.", with "\\d\\."
Spaces can be found using "\\s".
You can search for a word by simply using the word as your pattern. pattern = 'word'

Using grep(), print the text of the responses that contained a numeric number.
Find all items with a number followed by a space. Use a regular expression for the number and the space.
Use length() and grep() to find out how many times you wrote down the word "favorite".
