| match {BiocGenerics} | R Documentation |
match returns a vector of the positions of (first) matches of
its first argument in its second.
NOTE: This man page is for the match S4 generic function
defined in the BiocGenerics package.
See ?base::match for the default method
(defined in the base package).
Bioconductor packages can define specific methods for objects
(typically vector-like) not supported by the default method.
match(x, table, nomatch=NA_integer_, incomparables=NULL, ...)
x, table |
Vector-like objects (typically of the same class, but not necessarily). |
nomatch, incomparables |

... |
Additional arguments, for use in specific methods. |
The same as the default method, that is, an integer vector of the same
length as x giving the position in table of the first match
if there is a match, otherwise nomatch.
See ?base::match for more details.
Specific methods defined in Bioconductor packages should behave as consistently as possible with the default method.
The default method (defined in the base package) doesn't have the
... argument. We've added it to the generic function defined
in the BiocGenerics package in order to allow specific methods to
support additional arguments if needed.
base::match for the default match method.
showMethods for displaying a summary of the
methods defined for a given generic function.
selectMethod for getting the definition of
a specific method.
match,Hits,Hits-method in the S4Vectors
package for an example of a specific match method (defined
for Hits objects).
