select()

The select() function will select specific columns (variables) in a data frame. This may be useful when a data frame has many variables and you only want to take a look at a few of them together, or save a subset of variables as a new data frame.

NOTE: The select() function selects columns. To select specific rows, see the filter() function.

Example 1:

# Select only the columns for Thumb, Sex, and RaceEthnic in Fingers

# Optional: Use head() to truncate the output

head(select(Fingers, Thumb, Sex, RaceEthnic))

Example output:

Example 2:

# Save a selected set of variables as a new data frame called Fingers_subset

Fingers_subset <- select(Fingers, Thumb, Index, Middle, Ring, Pinkie)

head(Fingers_subset)

Example output:
