Take a look at ?assign

I had to do the same thing many times, i usually use a combination of the
functions "eval", "parse" and "sprinf", as below:
k <- 1
for (i in 1:length(stats$hour)) {
eval(parse(text=sprintf("x%s <- dataset[%s,(3:15)]", i, k)))
k <- k+1
}
what it does is:
eval(parse(text=STRING)) is a way to execute what is written on STRING
and
sprintf("TEXT%sTEXT", VARIABLE) substitutes the %s part of the text in the
first argument for whatever is on the second argument (you can extend this to
many %s parts)
Note: i've changed the "=" for the "<-" because someone told me that it was
more correct (don't ask me why though!).

Hello,
I am trying to assign a variable name (x1,x2,x3...) in a loop statement
that is based on a counter (counter is based on the number of hours
within the datafile). The x1,x2 data will later be called for plotting
the data. Below is a clip of the for loop I am using, any suggestions?
k = 1
for (i in 1:length(stats$hour)) {
"x(i)" = dataset[k,(3:15)]
k = k+1
}
Thanks,
Doug
