Dear Gabor Grothendieck,
thank you for your comments.
Ive already tried that. but I've got this error message.
Reduce("+",z)
Error in f(init, x[[i]]) : non-numeric argument to binary operator
> Reduce("+", c( LL[[1]], LL[[2]] ) )
[,1] [,2] [,3] [,4] [,5]
[1,] 6 36 66 96 126
[2,] 12 42 72 102 132
[3,] 18 48 78 108 138
[4,] 24 54 84 114 144
[5,] 30 60 90 120 150
anyway, thanks
ps.
is.matrix(z[[1]][[1]])
[1] TRUE
I guess the reason "Reduce" doesn't work is that it has multi-
dimentional
list..

Dear R users,
I have the list as follows;
#------------------------------------------------------
z
[[1]]
[[1]][[1]]
matrix(A)
[[1]][[2]]
matrix(B)
[[1]][[3]]
matrix(C)
[[2]]
[[2]][[1]]
matrix(D)
[[2]][[2]]
matrix(E)
[[2]][[3]]
matrix(F)
#---------------------------------------------
I'd like to compute
matrix(A)+matrix(B)+matrix(C)+matrix(D)+matrix(E)+matrix(F)
In fact, I tried "lapply", "do.call" etc, but failed.
Any suggestion will be greatly appreciated.
Regards,
Kathryn Lord
