Hello,
In help(clusterApply) of the 'parallel' package, it says:
"clusterApply calls fun on the first node with arguments seq[[1]] and ..., on
the second node with seq[[2]] and ..., and so on, recycling nodes as needed."
But the argument that is iterated over in clusterApply() is called 'x' not
'seq', so shouldn't it read x[[1]], x[[2]], and so on?
Also, 'x' doesn't have to be a vector ("x - a vector for clusterApply and
clusterApplyLB, a matrix for parRapply and parCapply."), it just needs to be an
object for which x[[1]], x[[2]], ... works (e.g., a data frame works just fine).
"clusterApplyLB is a load balancing version of clusterApply. If the length p of
seq is not greater than the number of nodes n, then a job is sent to p nodes."
Again, shouldn't that say "If the length p of x"?
And finally, "For clusterApply and clusterApplyLB, a list the same length as
seq." Again, 'x' instead of 'seq'?
Best,
Wolfgang
