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

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

new_rivers <- sample(rivers, 5)
 new_rivers
-
## [1]  730 1885  424  560  500
+
## [1] 1054  250  291  300  230

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

new_rivers + 1
-
## [1]  731 1886  425  561  501
+
## [1] 1055  251  292  301  231

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]  731 1886  425  561  501
+
## [1] 1055  251  292  301  231

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.

Make sure you run something like this, with the <- operator:

rivers2 <- new_rivers + 1
