I have a data set , say, X :  
mean 0 .8
sd 1 3
I need to use it in do.call() , so when I refer to the first col of X, I need it to be a list with members mean, sd.
thus I constructed X as a list of list : X[]<- list(mean=0, sd=1), X[]<-..... . But this dataset is useless in other
cases, for example, I can't pull out all the means as a vector.
Can I get some suggestions on what's the best way to handle it? (except preparing two copies of this data with different formats)
Thanks a lot in advance.
