Dear Folks --
The anonymous poster (rmailbox) is perfectly correct. I had forgotten you
could use names in this way. When referring to rows or columns by name
rather than by number, I usually use either attach() or the $ operator,
neither of which works here. If anyone understands why

Hello
I would like to use SNOW to parallelise some computations to be made on columns
of a data frame, using different parameter values for each SNOW worker.
I gather(?) clusterMap() is the appropriate SNOW function to do something like
this. I suspect the problem lies in the fact that I am
Hi, Agustin,
I also encountered similar problems when cutting trees. However, I think one
himself/ herself has to figure out the components of each cluster. The
labels that are generated by the current packages simply only distinguish
one cluster from another, but do not have more meanings.

The default arguments are:

you are making nsim=4 (this parameter is not the size of each sample, it

This one seems to have slipped through the cracks, but I'll take a stab at
it:
I don't think there's an (easy) general solution but there are two direct
ways to get at the idea.
If you are generally only seeking to do things like: x[order(x)] would
sort(x) work for you?
More generally, this can
How are your time samples missing?
If they are recorded as NA, the na.locf() function will fill them with the
previous value (zero-order hold) and with the reversability arguments can
give linear interpolation:

x = c(1:5,NA,6:10)
x = xts(x,Sys.Date()+0:10)

Hi Eran,
You have already gotten some suggestions from Michael, but I think
that Rich is correct to question the rational. Any mechanism you
choose to replace the missing values will impose its structure on the
data. Veritate ab absurdo:

Try playing with match(). Something like
d[match(v,d[,1]),2]
Should work (untested bc I'm writing from my phone though)

Could you repaste your data using dput() so we can see exactly what we are
working with here.
As things stand currently, I can't tell why it doesn't suffice to just
combine the dates and times into POSIX objects and subtract them all from
the first row. For more information on that approach, try
