summarise_each {dplyr} | R Documentation

## Summarise and mutate multiple columns.

### Description

`mutate_each()` and `summarise_each()` are deprecated in favour of a more featureful family of functions: `mutate_all()`, `mutate_at()`, `mutate_if()`, `summarise_all()`, `summarise_at()` and `summarise_if()`.

The `_each()` functions have two replacements depending on what variables you want to apply `funs` to. To apply a function to all variables, use `mutate_all()` or `summarise_all()`. To apply a function to a selection of variables, use `mutate_at()` or `summarise_at()`.

See the relevant section of `vignette("compatibility")` for more information.

### Usage

    summarise_each(tbl, funs, ...)

    summarise_each_(tbl, funs, vars)

    mutate_each(tbl, funs, ...)

    mutate_each_(tbl, funs, vars)

    summarize_each(tbl, funs, ...)

    summarize_each_(tbl, funs, vars)
