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 ./. P:S Sorry for my English
