They want a preview of just the first six rows to get a better idea of how the data frame is laid out. What function should they use? You are working with the ToothGrowth dataset. You want to use the head() function to get a preview of the dataset. Write the code chunk that will give you this preview.head(ToothGrowth)What are the names of the columns in the ToothGrowth dataset? A data analyst is working with a data frame named customers. It has separate columns for area code (area_code) and phone number (phone_num). The analyst wants to combine the two columns into a single column called phone_number, with the area code and phone number separated by a hyphen. What code chunk lets the analyst create the phone_number column? A data analyst wants to find out how much the predicted outcome and the actual outcome of their data model differ. What function can they use to quickly measure this? A data analyst is considering using tibbles instead of basic data frames. What are some of the limitations of tibbles? Select all that apply.
