Dear list,
I am trying to find the way to add columns to a table
(or a matrix) after a loop. The result of this loop is
an array and I would like to get all the results in a
single table once the loop is finish. I have
reproduced a simplified example below:
a- 1
b - matrix()
while (a = 4) {
+ b-rnorm(10)
+ a- a +1
+ }
Staying in your example:
a - 1
b - matrix(nrow=10, ncol=4)
while(a = 4){
b[,i] - rnorm(10)
a - a + 1
}

# I have tried several methods but without succes so
far.
result - as.data.frame(cbind(b))
result
b
1 -0.03250661
2 -0.59823770
3 1.58120471
4 0.41086546
5 0.78959090
6 1.23587125
7 0.83427190
8 1.09035581
9 0.11331056
10 0.25267231
the result above is not what I am looking for because
it shows only the results from the last operation in
the loop, I would like to obtain something like the
following.
result
b1 b2 b3 b4
1 -0.08420826 -0.0637943 -0.83246201 -1.0902384

10 1.51942415 -0.2051423 0.09144450 -1.6329481
I hope someone can give me a hand
