| rank {BiocGenerics} | R Documentation |
Returns the ranks of the values in a vector-like object. Ties (i.e., equal values) and missing values can be handled in several ways.
NOTE: This man page is for the rank
S4 generic function defined in the BiocGenerics package.
See ?base::rank for the default method
(defined in the base package).
Bioconductor packages can define specific methods for objects
not supported by the default method.
rank(x, na.last=TRUE,
ties.method=c("average", "first", "last", "random", "max", "min"),
...)
x |
A vector-like object. |
na.last, ties.method |

Additional arguments, for use in specific methods. Note that |
See ?base::rank for the value returned
by the default method.
Specific methods defined in Bioconductor packages should behave as consistently as possible with the default method.
TO DEVELOPERS:
See note in ?BiocGenerics::order
about "stable" order.
order, sort,
and rank methods for specific vector-like
objects should adhere to the same underlying order that should be
conceptually defined as a binary relation on the set of all possible
vector values. For completeness, this binary relation should also be
incarnated by a <= method.
base::rank for the default rank method.
showMethods for displaying a summary of the
methods defined for a given generic function.
selectMethod for getting the definition of
a specific method.

Vector objects).
