## Usage

```
as_long(from, ...)
# S4 method for matrix
as_long(from, factor = FALSE, reverse = FALSE)
confidence(object, ...)
# S4 method for numeric
confidence(object, level = 0.95, type = c("student", "normal"))
assert_numeric(x, expected, ...)
assert_trend(x, expected, ...)
assert_relation(x, y, expected, ...)
assert_matrix(x, expected)
remove_empty(x, margin = 1)
```

## Arguments

- from
An object to be coerced.

- ...
Extra parameters to be passed to internal methods.

- factor
A

`logical`

scalar: should character string be coerced to`factor`

? Default to`FALSE`

, if`TRUE`

the original ordering is preserved.- reverse
A

`logical`

scalar: should the order of factor levels be reversed? Only used if`factor`

is`TRUE`

. Useful for plotting.- object
A

`numeric`

vector.- level
A length-one

`numeric`

vector giving the confidence level. Must be a single number between \(0\) and \(1\).- type
A

`character`

string giving the type of confidence interval to be returned. It must be one "`student`

" (the default) or "`normal`

". Any unambiguous substring can be given.- x, y
A

`numeric`

object to be checked.- expected
A

`character`

string specifying the expected value (see details).- margin
A vector giving the subscripts which the function will be applied over (

`1`

indicates rows,`2`

indicates columns).
