binning {bda} | R Documentation |
To bin a univariate data set in to a consecutive bins.
binning(x, counts, nclass, breaks, bw)
x |
A vector of raw data. 'NA' values will be automatically removed. |
counts |
Frequencies or counts of observations in different classes (bins) |
nclass |
Number of classes |
breaks |
The break points for data binning. |
bw |
Bin (class) width. |
Data binning can be done in the following cases:
(1) both x
and breaks
are specified;
(2) both counts
and breaks
are specified;
(3) both x
and bw
are specified.
If (3a) breaks
is of length 1, it gives the lower limit
of the first bin/class, and a sequence of equal-width bins will
be defined.
If (3b) breaks
is missing, a random starting point will
be chosen.
x
and counts
cannot be both given.
nclass
will not be used if x
is missing.
