I think I got what you mean, so that I can't use the 
"Wealth1[[s]][i] <- Ca[i+1]+Po[i+1]"
in the last line of loops.

Is there any code I can use the store the data?
I aim to store the data like :
a <- "x1" "x2" "x3" "x4" ...
and in each entry of a
x1 <- 1  2  3  4  5  6  7  ...
the entries in "x1" are the "wealth" that I want estimate.
Please tell me the code to store these type of data. Thanks. :)

actually I can create the Price[[i]] by coding "Price = list()" before I
simulate the price
