 # Working with checkpoint archive snapshots
 
 You can query the available snapshots on disk using the `checkpointArchives()` function. This returns a vector of snapshot folders. 
 
 
-```{r archives-1}
+```r
 # List checkpoint archives on disk.
 checkpointArchives(tempdir())
 ```
+```
+## [1] "2017-04-01"
+```
 
 You can get the full paths by including the argument `full.names=TRUE`:
 
-```{r archives-2}
+```r
 checkpointArchives(tempdir(), full.names = TRUE)
 ```

 ## Working with access dates
 
 Every time you use `checkpoint()` the function places a small marker in the snapshot archive with the access date. In this way you can track when was the last time you actually used the snapshot archive.
 
-```{r access}
+```r
 # Returns the date the snapshot was last accessed.
 getAccessDate(tempdir())

 The function `checkpointRemove()` will delete archives from disk. You can use this function in multiple ways. For example, specify a specific archive to remove:
 
-```{r remove-1, eval=FALSE}

+```r
+# Remove single checkpoint archive from disk.

 # Resetting the checkpoint
 
-In older versions of `checkpoint()` the only way to reset the effect of `checkpoint()` was to restart your R session.
