This is an efficient implementation of the common pattern of `do.call(rbind, dfs)` or `do.call(cbind, dfs)` for binding many data frames into one.
This is an efficient implementation of the common pattern of `do.call(rbind, dfs)` or `do.call(cbind, dfs)` for binding many data frames into one.
`bind_rows()` and `bind_cols()` return the same type as the first input, either a data frame, `tbl_df`, or `grouped_df`.
`bind_rows()` and `bind_cols()` return the same type as the first input, either a data frame, `tbl_df`, or `grouped_df`.
The output of `bind_rows()` will contain a column if that column appears in any of the inputs.
The output of `bind_rows()` will contain a column if that column appears in any of the inputs.
# Note: "dplyr" does not provide a generic function for `bind_rows`. Therefore, the generic
# function `bind_rows` located in "ttservice" should be called explicitly with
# `ttservice::bind_rows` to avoid conflicts.
