R: Provide a succinct summary of an object

obj_sum {tibble} | R Documentation

## Provide a succinct summary of an object

### Description

`type_sum()` gives a brief summary of object type. Objects that commonly occur in a data frame should return a string with four or less characters.

`obj_sum()` also includes the size of the object if `is_vector_s3()` is `TRUE`.

`tbl_sum()` gives a brief textual description of a table-like object, which should include the dimensions, the data source, and possible grouping (for `dplyr`). The default implementation forwards to `obj_sum()`.

### Usage

    obj_sum(x)

    type_sum(x)

    tbl_sum(x)

    is_vector_s3(x)

### Arguments

`x` | an object to summarise. Generally only methods of atomic vectors and variants have been implemented.

### Examples

    obj_sum(1:10)
    obj_sum(matrix(1:10))
    obj_sum(Sys.Date())
    obj_sum(Sys.time())
    obj_sum(mean)
