Why are my changes not taking effect? It’s making my results

Here we are creating a new object from an existing one:

new_rivers <- sample(rivers, 5)
 new_rivers
-
## [1] 529 246 291 540 237
+
## [1]  310  325  900 1770  217

Using just this will only print the result and not actually change new_rivers:

new_rivers + 1
-
## [1] 530 247 292 541 238
+
## [1]  311  326  901 1771  218

If we want to modify new_rivers and save that modified version, then we need to reassign new_rivers like so:

new_rivers <- new_rivers + 1
 new_rivers
-
## [1] 530 247 292 541 238
+
## [1]  311  326  901 1771  218

If we forget to reassign this can cause subsequent steps to not work as expected because we will not be working with the data that has been modified.
