How to add column to dataframe Note, when adding a column with tibble we are, as well, going to use the %>% operator which is part of dplyr.

Therefore, when we speak of data frames we also mean tibbles. To create a new tibble from combining multiple vectors, use the function data_frame (): friends_data <- data_frame(name = c("Nicolas", "Thierry", "Bernard", "Jerome"), age = c(27, 25, 29, 26), height = c(180, 170, 185, 169), married = c(TRUE, FALSE, TRUE, TRUE)) friends_data problem converting tibble to data.frame #175.
