Coerce to a Data Frame

S3 method for quantities objects (see as.data.frame).

Usage

# S3 method for quantities
as.data.frame(x, row.names = NULL, optional = FALSE,
  ...)

Arguments

x

any R object.

row.names

NULL or a character vector giving the row names for the data frame. Missing values are not allowed.

optional

logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.

...

additional arguments to be passed to or from methods.

Examples

x <- set_quantities(1:3, m/s, 0.1)
y <- set_quantities(4:6, m/s, 0.2)
(z <- cbind(x, y))
#> Units: [m/s]
#> Errors: 0.1 0.1 0.1 0.2 0.2 ...
#>      x y
#> [1,] 1 4
#> [2,] 2 5
#> [3,] 3 6
as.data.frame(z)
#>              x            y
#> 1 1.0(1) [m/s] 4.0(2) [m/s]
#> 2 2.0(1) [m/s] 5.0(2) [m/s]
#> 3 3.0(1) [m/s] 6.0(2) [m/s]
