(Details of your nice example code removed)
a=replicate(3, list(list(c(1,1,1), diag(3), c(2,2,2))))
str(a) # I prefer this to print(a) because it shows the structure better
# in steps
b = lapply(a,function(x){
# print(str(a)) # put this here to know what you are doing
x[2:3]
}
)
#... mmm, not yet what you wanted. Another try
b[1:2]
# I leave it as a easy exercise to jam this into a one-liner
