List Structure and Acces to data

Hello,

I used some other langages as Matlab and i just began with R, and i need help with data structure.

Here is my code

"
fct_echant_hist <- function ( my_echant, my_vitesse, my_hist, my_summary) {
          list (my_echant = my_echant,
                my_vitesse = my_vitesse,
                my_hist = my_hist,
                my_summary = my_summary)}


my_echant_hist <- replicate(dim(pas)[1], fct_echant_hist(0L,
                           0L,
                           matrix(nrow=length(my_breaks),ncol=1),
                           matrix(nrow=6,ncol=1)),
           simplify=FALSE)
"
Is it possible to acces to all data of my_vitesse ?


to acces to the my_vitesse of the first record i write
my_echant_hist[[1]][[2]]

I try something like that without succes :
my_echant_hist[[]][[2]] or
my_echant_hist[[:]][[2]] or
my_echant_hist[[;]][[2]]


Thanks a lot

Eric ./.
