grep
and grepl
S4 generic functions defined in the BiocGenerics package.
See ?base::grep
for the default methods
(defined in the base package).
Bioconductor packages can define specific methods for objects
not supported by the default method.
grep(pattern, x, ignore.case = FALSE, perl = FALSE, value = FALSE, fixed = FALSE, useBytes = FALSE, invert = FALSE)
grepl(pattern, x, ignore.case = FALSE, perl = FALSE, fixed = FALSE, useBytes = FALSE)
x
, such as a regular expression.
?base::grep
for a description of
these arguments.
?base::grep
for the value returned
by the default method.Specific methods defined in Bioconductor packages should
behave as consistently as possible with the default method.
base::grep
for the default
grep
and grepl
methods.
showMethods
for displaying a summary of the
methods defined for a given generic function.
selectMethod
for getting the definition of
a specific method.
grep # note the dispatch on 'pattern' and 'x' args only
showMethods("grep")
selectMethod("grep", "ANY") # the default method
