Description Usage Arguments Details Value Examples
This function returns the "typical" value of a variable.
1 | typical_value(x, fun = "mean", weights = NULL, ...)
|
x |
A variable. |
fun |
Character vector, naming the function to be applied to
|
weights |
Name of variable in |
... |
Further arguments, passed down to |
By default, for numeric variables, typical_value()
returns the
mean value of x
(unless changed with the fun
-argument).
For factors, the reference level is returned or the most common value
(if fun = "mode"
), unless fun
is a named vector. If
fun
is a named vector, specify the function for integer, numeric
and categorical variables as element names, e.g.
fun = c(integer = "median", factor = "mean")
. In this case,
factors are converted to numeric values (using to_value
)
and the related function is applied. You may abbreviate the names
fun = c(i = "median", f = "mean")
. See also 'Examples'.
For character vectors the most common value (mode) is returned.
The "typical" value of x
