bpmapply
Parallel mapplylike functionality
bpmapply
applies FUN
to first elements of ...
,
the second elements and so on. Any type of object in ...
is
allowed, provided length
, [
, and [[
methods are
available. The return value is a list
of length equal to the
length of all objects provided, as with mapply
.

Usage
bpmapply(FUN, ..., MoreArgs=NULL, SIMPLIFY=TRUE, USE.NAMES=TRUE, BPREDO=list(), BPPARAM=bpparam())
"bpmapply"(FUN, ..., MoreArgs=NULL, SIMPLIFY=TRUE, USE.NAMES=TRUE, BPREDO=list(), BPPARAM=bpparam())
"bpmapply"(FUN, ..., MoreArgs=NULL, SIMPLIFY=TRUE, USE.NAMES=TRUE, BPREDO=list(), BPPARAM=bpparam())
Arguments
 FUN
 The
function
to be applied to each element passed via...
.  ...
 Objects for which methods
length
,[
, and[[
are implemented. All objects must have the same length or shorter objects will be replicated to have length equal to the longest.  MoreArgs
 List of additional arguments to
FUN
.  SIMPLIFY

If
TRUE
the result will be simplified usingsimplify2array
.  USE.NAMES
 If
TRUE
the result will be named.  BPPARAM
 An optional
BiocParallelParam
instance defining the parallel backend to be used during evaluation.  BPREDO
 A
list
of output frombpmapply
with one or more failed elements. When a list is given inBPREDO
,bpok
is used to identify errors, tasks are rerun and inserted into the original results.

Value

bpvec
for parallel, vectorized calculations.

for possible values of BPPARAM
.
Examples
showMethods("bpmapply")
fun < function(greet, who) {
paste(Sys.getpid(), greet, who)
}
greet < c("morning", "night")
who < c("sun", "moon")
param < bpparam()
original < bpworkers(param)
bpworkers(param) < 2
result < bpmapply(fun, greet, who, BPPARAM = param)
cat(paste(result, collapse="\n"), "\n")
bpworkers(param) < original
