Question

you are working with the toothgrowth dataset. you want to use the select() function to view all columns except the supp column. write the code chunk that will give you this view.

Answer 1

To exclude the 'supp' column from the 'toothgrowth' dataset in R using 'select()', use the code 'toothgrowth %>% select(-supp)'. This removes the specified column from the results, displaying all others.

Step-by-step explanation:

To view all columns except the supp column from the toothgrowth dataset using the select() function from the dplyr package in R, you need to use a special helper function. The helper function everything() can be used along with the minus sign to exclude a particular column.

The following code snippet demonstrates how to do this:

toothgrowth %>%
select(-supp)
This code uses the pipe operator (%>%) to pass the toothgrowth data frame to the select() function, where -supp indicates that the supp column should be excluded from the results.

Answer 2

To view all columns in the toothgrowth dataset except the 'supp' column, use the 'select(toothgrowth, -supp)' function from the dplyr package in R.

Step-by-step explanation:

If you are working with the toothgrowth dataset in R and would like to view all columns except the supp column, you can use the select() function from the dplyr package along with the minus sign to exclude the desired column. Here's the code chunk that will provide the requested view:

library(dplyr)
# Assuming 'toothgrowth' is your dataframe
toothgrowth_minus_supp <- select(toothgrowth, -supp)

The -supp argument is used within the select() function to indicate that we want to exclude the 'supp' column from the resulting dataframe. After running this code, toothgrowth_minus_supp will contain all the columns from the original 'toothgrowth' dataframe except the 'supp' column.
