| clusterApply {BiocGenerics} | R Documentation |
These functions provide several ways to parallelize computations using a cluster.
NOTE: This man page is for the clusterCall, clusterApply,
clusterApplyLB, clusterEvalQ, clusterExport,
clusterMap, clusterSplit, parLapply, parSapply,
parApply, parRapply, parCapply, parLapplyLB,
and parSapplyLB S4 generic functions defined in the
BiocGenerics package.
See ?parallel::clusterApply for the default
methods (defined in the parallel package).
Bioconductor packages can define specific methods for cluster-like
objects not supported by the default methods.

See ?parallel::clusterApply for the value returned
by the default methods.
Specific methods defined in Bioconductor packages should behave like the default methods.
parallel::clusterApply for the default
methods.
showMethods for displaying a summary of the
methods defined for a given generic function.
selectMethod for getting the definition of
a specific method.
