| CentralValue {DescTools} | R Documentation |
This function obtains a statistic of centrality of a variable given a sample of its values.
CentralValue(x, ws = NULL)
x |
A vector of values (the sample). |
ws |
A vector of case weights (defaulting to NULL, i.e. no case weights). |
If the variable is numeric it returns de median of the given sample, if it is a factor it returns the mode. In other cases it tries to convert to a factor and then returns the mode.
A number if the variable is numeric. A string with the name of the most frequent nominal value, otherwise.
