2.The data set penguins_raw contains data collected on several species of penguins in Antarctica. (You will need to install and load the package `palmerpenguins`.)

a.The variable `studyName` contains an identifier of the particular study that produced the data for that penguin. Split that variable into two variables: one that contains the alphabetic portion and one that contains the numeric portion.

b.The variable `Individual ID` has a format that starts with the letter N, followed by numbers, and then the letter A, and then more numbers. The numbers following the N indicate the nest number. Create a variable containing only the numbers immediately following the N.
