[R] Iterating Named List

Hi all,

I have the following named list:

> print(y)

$`200052_s_at`
[1] -1066.975 -1063.893 -1062.815 -1062.121 -1059.004

$`200071_at`
[1] -959.823 -953.980 -953.886 -948.781 -974.890

$`200084_at`
[1] -1135.804 -1132.863 -1128.197 -1128.633 -1125.890

What I want to do is to iterate this name list and process its members. To do that I attempt the following code (but failed):

__BEGIN__
ny <- names(y)

for (i in ny) {

   val <- paste("`",i,"`",sep="")
   print(y$val)

   # later we want to process y$val
}

__END__
However the after printing it gives "NULL". What's wrong with my code above?
