The example ducks that issue. Someone needs to write a function for
merging these results. Probably just involves making a suitable call
to boot.return, which is what happens at the end of boot(), but I
don't know if anyone has actually done this yet.

Hello,
I'm trying to do some bootstrapping in a parallel environment (Linux
cluster) in order to estimate confidence intervals for a certain
parameter. Following the example in the documentation of the snow
package (http://www.stat.uiowa.edu/~luke/R/cluster/cluster.html), I
launch my computations by something like
cl.nuke.boot -
+ clusterCall(cl,boot,nuke.data, nuke.fun, R=500, m=1,
+ fit.pred=new.fit, x.pred=new.data)
which gives me a list of n boot objects (where n is the number of nodes
in my cluster). So far, so good.
However, if I now want to go further, I need to combine all these boot
objects to a single one which I can pass to boot.ci for example. Is
there a recommended way to do this?
Thanks,
Michael
