classnum: Gives an index vector of the class category of each value of a numerical vector
Description
Gives an index vector of the class category of each value of a numerical vector
Usage
classnum(x, breaks = "Sturges")
Value
A vector of the same length as x, with the index of the class which each value of x belongs to
Arguments
x
a vector of values for which the indices are desired
breaks
one of:
a vector giving the breakpoints between bins,
a single number giving the number of bins,
a character string naming an algorithm to compute the number of cells (see Details).
Details
The default for 'breaks' is '"Sturges"': see 'nclass.Sturges'. Other names for which algorithms are supplied are '"Scott"' and
'"FD"' for '"Friedman-Diaconis"' (with corresponding functions 'nclass.scott' and 'nclass.FD'). Case is ignored and partial matching is used.
Breaks and labels are stored as attributes.
