merge multiple array in R

  merge_arrays <- function(list_x) {
    arr_out <- list_x[[1]]
    for (i in seq_along(list_x[-1])) {
      arr_out <- c(arr_out, list_x[[i]])
    }
    return(arr_out)
  }

This code is a function for merging multiple arrays in R. It takes a list of arrays as its argument and returns a single combined array. The first line sets up the function, and the next line stores the first array in the list in a new array. The for loop then takes each array in the list, one at a time, and concatenates it with the rest of the arrays already present in the new array. Finally, the combined array is returned.
