I should have said: The below only works if you can get it into the
function code. If you cannot, and the function has no options that
allow you to limit execution time or iterations, then I don't see how
you can do it.

?proc.time
e.g. something like
time0 - proc.time()[2]
state - not converged
while(proc.time()[2] time0[2] + 600 ) ## 10 minutes

##... Do your thing...
if(get an answer) {state - converged; break}
}
Refinement required, but you get the idea.

Hello all,
I'm running a parameter grid optimization ( ksvm, kernlab package) and the
optimizer
seems not to converge for certain parameters and stays in a infinity loop.
Would it be possible to abort the execution after x-seconds and continue
with the next parameter set? Which R function do need to use to accomplish
this?
I had a look at, try() etc. but they didn't seem so fit my needs.
I would appreciate any suggestions..
best regards

possible to reach the ultimate truths without the elementary studies
usually prefixed to them, these would not be preparatory studies but
superfluous diversions.
