I don't know of any such option, but it's easy enough to achieve something more
or less equivalent.
x <- runif(5)
for (ir in seq(nrow(myi <- cbind(x, 1:length(x))))) {
i <- myi[ir,1]
j <- myi[ir,2]
cat(i,j,'\n')
}
I consider that for() statement to be ugly and unreadable. Normally I would
build the matrix myi before constructing the loop, and make other changes for
clarity. But in this instance I wanted to make it a one-liner, just to more or
less mimic the python.
And having now read Bert's reply, he makes a good point. For many things one
might want to do with such a loop, R can do them without an explicit loop.

Hello,
Is there an option to include multiple counters in a single for loop in R?
For instance, in python there is
for i,j in zip(x,range(0,len(x))):
Any suggestions?
