The problem is that there isn't an "as.name<-" function so you can't use
as.name on the left-hand side of an assignment. 

You probably mean 
   assign(paste("myvar","1",sep="."),1:10)
but your life might well be easier if you just had a list called myvar and
had vectors myvar[[1]], myvar[[2]], and so on.
