Store 10 values in R

Question

Good morning everyone, I have to do an exercise where I have to store 10 values typed repeatedly and say how many are negative and positive. I need to use the while command but don’t know how to store these values.

Answer 1

Try the following:

conta <- 0
x <- numeric(0)
while(conta < 10){
    y <- scan(nmax = 1)
    x <- c(x, y)
    conta <- conta + 1
}

positivo <- x[x > 0]
negativo <- x[x < 0]
zero <- x[x == 0]

Now if you want to know how many are the positive, negative or zero (which is missing in the question?) just use length.

length(positivo)
length(negativo)
length(zero)

To see them,

positivo
negativo
zero
