labels {relations} | R Documentation |
Creates “nice” labels from (vector-like) objects.
LABELS(x, max_width = NULL, dots = "...", unique = FALSE) LABEL(x)
x |
For LABELS , a vector of R objects (if the object is
not a vector, it is converted to a list of length 1).
For LABEL , an R object. |
max_width |
Integer vector (recycled as needed) specifying the
maximum label width for each component of x .
If NULL , there is no limit, otherwise, the label will be
truncated to max_width . |
dots |
A character string appended to a truncated label.
If NULL , nothing is appended. |
unique |
Logical indicating whether
make.unique should be called on the final
result. |
A character vector of labels generated from the supplied object(s).
LABELS
first checks whether the vector has names and uses these
if any; otherwise, LABEL
is called for each element to generate
a “short” representation.
LABEL
is generic to allow user extensions.
The current methods return the result of format
if the
argument is of length 1 (for objects of classes set
and
tuple
: of length 5), and create a simple class
information otherwise.
LABELS(list(1, "test", X = "1", 1:5)) LABELS(set(X = as.tuple(1:20), "test", list(list(list(1,2))))) LABELS(set(pair(1,2), set("a", 2), as.tuple(1:10)))
