[BioC] How can I create a variable with name indicated by argument during function run?

[Kasper Daniel Hansen]

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
