| dimrename {memisc} | R Documentation |
These functions provide an easy way to change the dimnames, rownames or colnames of
an array.
dimrename(x, dim = 1, ..., gsub = FALSE, fixed = TRUE, warn = TRUE) rowrename(x, ..., gsub = FALSE, fixed = TRUE, warn = TRUE) colrename(x, ..., gsub = FALSE, fixed = TRUE, warn = TRUE)
x |
An array with dimnames |
dim |
A vector that indicates the dimensions |
... |
A sequence of named arguments |
gsub |
a logical value; if TRUE, gsub is used to change the
dimnames of the object.
That is, instead of substituting whole names, substrings of the
dimnames of the object can changed.
|
fixed |
a logical value, passed to gsub. If TRUE,
substitutions are by fixed strings and not by regular expressions. |
warn |
logical; should a warning be issued if the pattern is not found? |
dimrename changes the dimnames of x along dimension(s) dim according to the
remaining arguments. The argument names are the old
names, the values are the new names.
rowrename is a shorthand for changing the rownames,
colrename is a shorthand for changing the colnames of a matrix
or matrix-like object.
If gsub is FALSE, argument tags are the old
dimnames, the values are the new dimnames.
If gsub is TRUE, arguments are substrings of the dimnames
that are substituted by the argument values.
Object x with changed dimnames.
