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]  680  390 2348  410  890
+
## [1] 1270  350  435  265  250

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

new_rivers + 1
-
## [1]  681  391 2349  411  891
+
## [1] 1271  351  436  266  251

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]  681  391 2349  411  891
+
## [1] 1271  351  436  266  251

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.

Error: object ‘X’ not found

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

rivers2 <- new_rivers + 1
 rivers2
