Saving results from for loop as a vector in r
Alternatively
my_vector = c()
for(i in 1:5){my_vector=c(my_vector,i)}
my_vector
Calling print
will always print the result of each iteration to the console. If you leave in the print
command, then you might get unwanted output.
Your main problem is that you did not initialize my_vector
before the for
loop. You could instead do the following and not get the print
side-effect.
my_vector <- vector("numeric", 10L)
for(i in 1:10) my_vector[i] <- i
my_vector
# [1] 1 2 3 4 5 6 7 8 9 10
But note that this is just the same as doing the following with sapply
, but in this case you need no declaration and you can assign the result to a vector.
my_vector2 <- sapply(1:10, function(x) x)
my_vector2
# [1] 1 2 3 4 5 6 7 8 9 10
