fun
n
argfun
dependsStep

dependencies in 1..n

initVal

results presented to argfun for the first 1..dependsStep results

freeMasterNode

if set to TRUE, no job is submitted to node 1, so that this node can dispatch jobs without waiting

argfun=function(i,prevRes) list( <args(i,prevRes)> ) provides arguments to fun where

i

index for which to generate arguments

prevRes
