If you want to assign a value to a character-name you need to use ... `assign`.
You cannot just stick a numeric value which is what you get with sys.Time() on
the LHS of a "<-" and expect R to intuit what you intend.
?assign
assign( "a_2012_09_27_00_12_30" , rnorm(1,2,1) )
assign( as.character(unclass(Sys.time())) , rnorm(1,2,1) )
(I would have thought you wanted to format that sys.Time result:)
> format(Sys.time(), "%Y_%m_%d_%H_%M_%S")
