Error in cut.default(i, breaks) : invalid number of intervals
This is because in parLapply length(cl) is determined before
defaultCluster(cl) is called. By inspection, this appears to be true of
other high-level functions, but ironically not of parApply.
In defaultCluster, t would also be helpful to check that the detected
cluster, user-supplied or other, is a valid cluster.
diff attached.
