 # how to use Xn list (X(1), X(2), X(3) variables in an equation and get the result automatically for all variables as a loop

good morning you'll,

I have a quick question and would really appreciate your help and suggestions
i am trying to use X(n) of numbers in an equation and result in Y(n) of the result for example:

I have X(1), X(2), X(3) variables as input
X(1) = 1
X(2) =3
X(3) =2
C =2
the equation is [ Y(n)= X(n)+C]

Y(1)= X(1)+C
Y(1)= 1+2
Y(1) = 3

Y(2)= 5
Y(3)= 4

I want to get the result of Y(1), Y(2), Y(3) all together
how can I use a loop to import X(1) value and get Y(1) value result and import X(2) value and get Y(2) value and so on.

Many functions in R are vectorized so you do not have to use explicit loops. For example, in the code below the constant C is added to each element of the vector X.

``````X <- c(1, 3, 2)
X
#>  1 3 2
C <- 2
Y <- X + C
Y
#>  3 5 4
``````
