+We have already seen several plot types above such as `"p"` (points), `"l"`

+plot types/elements available in base R, as well as a number of additional plot
+types that can be a bit tedious to code up manually. The full list of supported
+plot types can be viewed in

+## Saving plots
+
+A final point to note is that **tinyplot** offers convenience features for
+exporting plots to disk. Simply invoke the `file` argument to specify the
+relevant file path (including the extension type). You can customize the output
+dimensions (in inches) via the accompanying `width` and `height`
+arguments.^[The default dimensions are 7x7, with a resolution of 300 DPI.
+However, these too can be customized via the `file.width`, `file.height`, and
+`file.res` parameters in
+[`tpar()`](https://grantmcdermott.com/tinyplot/man/tpar.html).]
+
+```{r save_plot}
+#| eval: false
+tinyplot(
+  Temp ~ Day | Month, data = aq,
+  file = "aq.png", width = 8, height = 5
+)
+
+# optional: delete the saved plot
+unlink("aq.png")
+```
+
+Alongside convenience, the benefit of this native **tinyplot** approach (versus
+the traditional approach of manually opening an external graphics device, e.g.
+`png()`) is that all of your current graphic settings are automatically carried
+over to the exported file. Feel free to try yourself by setting some global
+graphics parameters via `tpar()` and then using `file` to save a plot.
