Short string representation for R objects

Source: R/string_repr.R

This is inspired by the python function repr and produces a short string representation of any R object that is suitable for logging and error messages. It is a generic so you can implement methods for custom S3 objects.

string_repr(x, width = 32, ...)

# S3 method for `function`
string_repr(x, width = 32L, ...)

# S3 method for data.frame
string_repr(x, width = 32L, ...)

# S3 method for matrix
string_repr(x, width = 32L, ...)

# S3 method for default
string_repr(x, width = 32L, ...)

Arguments

x

Any R object.
width

a scalar integer
...

passed on to methods

Value

a scalar character

Examples

string_repr(iris)

#> [1] "<data.frame 150x5>"
string_repr(LETTERS)

#> [1] "(A, B, C, D, E, F, G, H, I, J..)"
string_repr(LETTERS, 10)

#> [1] "(A, B..)"
