# R Save Results of Loop in Vector (Example Code)

In this tutorial you’ll learn how to store loop results in a vector in the R programming language.

## Example: Saving Output of for-Loop in Vector or Array

x <- numeric() # Empty numeric vector |

x <- numeric() # Empty numeric vector

for(index in 1:10) { # Start of for-loop out_now <- index^2 # Creating some output x <- c(x, out_now) # Appending result to vector } |

for(index in 1:10) { # Start of for-loop out_now <- index^2 # Creating some output x <- c(x, out_now) # Appending result to vector }

x # Returning resulting vector to console # [1] 1 4 9 16 25 36 49 64 81 100 |

x # Returning resulting vector to console # [1] 1 4 9 16 25 36 49 64 81 100
