x
| numeric vector or array. |
cutpoints
|
numeric vector whose values cutpoints[j]
== c[j] (after augmentation, see corr
below) are used for intervals.
|
symbols
|
character vector, one shorter than (the
augmented, see corr below) cutpoints .
symbols[j] == s[j] are used as ``code'' for
the (half open) interval (c[j], c[j+1]].
|
na
|
character or logical. How NAs are coded. If
na == FALSE , NA s are coded invisibly, including
the "legend" attribute below, which otherwise mentions NA coding.
|
eps
| absolute precision to be used at left and right boundary. |
corr
|
logical. If TRUE , x contains correlations.
The cutpoints are augmented by 0 and 1 and abs(x)
is coded.
|
show.max
|
If TRUE , or of mode character , the
maximal cutpoint is coded especially.
|
show.min
|
If TRUE , or of mode character , the
minmal cutpoint is coded especially.
|
lower.triangular
|
logical. If TRUE and x is a
matrix, only the lower triangular part of the matrix is coded
as non-blank.
|
diag.lower.tri
|
logical. If lower.triangular and
this are TRUE , the diagonal part of the matrix is shown.
|
noquote
and the same
dimensions as x
.
It has an attribute "legend"
containing a legend
of the returned character codes, in the form
c[1] `s[1]' c[2] `s[2]' ... `s[n]' c_[n+1]
where c[j] = cutpoints[j]
and
s[j] = symbols[j]
