Return the typical value of a vector
This function returns the "typical" value of a variable.
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.
