secondModes: Most common and second most common values
Description
Identifies the most common (multiple) modes for frequency vectors as well as the second most common values.
Usage
secondModes(V, pos=FALSE, tolerance=0.1)
Arguments
V
A frequency vector
pos
Categories of frequency vector (optional)
tolerance
Specify how similar values have to be to be treated as different (optional). Differences smaller than or equal to the tolerance are ignored.
Value
The function returns a list for the most common and the second most common value(s). The output corresponds to that of the modes function.
Details
This function identifies which positions of a frequency vector correspond to the mode(s) as implemented in the modes function. It also reports the second most common position in the same manner.
