You could use assign  but using assign  or get  is often a symptom of a programming structure that is not very R like  Typically  lists or matrices allow cleaner solutions    with a list   A  lt - lapply  1   10  function  x  d   rnorm  3    with a matrix   A  lt - matrix  rep  d  each   10    rnorm  30   nrow   10

Another option is using eval and parse  as in d   5 for  i in 1 10        eval parse text   paste  a   1 10      d   rnorm 3    sep     i
