BiocGenerics (version 0.18.0)

rank: Ranks the values in a vector-like object


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"))


A vector-like object.
na.last, ties.method
See ?base::rank for a description of these arguments.


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.
