Dear all,
I need to do a loop in R, but I am not sure the software is generating "n"
times the variables I request differently. When I ask to print the last matrix
created, I just can see the loop for n=1.
To be more precise, supose I need to simulate 10 times one variable and I want
to fit the 10 variables simulated in a matrix. I dont really know what I am
doing wrong, but I just can see 1 variable created.
Below follows an example of what I want:
rm(list=ls()) #remove almost everything in the memory
set.seed(180185)
#loop: create 10 times the variables (u1,u2,u3,u4,u5)
for (i in 1:10){
u1 <- c(runif(200,0,1))
u2 <- c(runif(200,0,1))
u3 <- c(runif(200,0,1))
u4 <- c(runif(200,0,1))
u5 <- c(runif(200,0,1))
u <- c(u1,u2,u3,u4,u5)
mu <- matrix(u, nrow=1000, ncol=1)
}
As you can see, when I print(mu), I just can see a matrix with the vector u in
one column. I also tried to increase the number of columns to 10 (or i), but
the matrix will have 10 times the same vector. And what I need is like a Monte
Carlo simulation, where I have to simulate 10 times the variables above.
Am I doing something wrong?
Thanks in advance!
