Re: How can I create a variable with name indicated by argument during function run?

Michael's answer is of course correct, but if the intention is not to
create it in the global environment, you typically use assign, like
  assign("tmp", 1:3)
will create a variable called tmp with the value 1:3.  assign supports an
envir argument, so you can set it to create it in the Global environment.

Like Michael, I am wondering why you want to do this, and I hope this is
not intended for code that ever has to be used by other people besides
yourself.

Best,
Kasper
