# Exporting Plots with ggsave()

### Usage

```r
ggsave("peng_scatterplot.png", plot = peng_scatter) # to use the default size

# or

ggsave("peng_scatter_2.png", plot = peng_scatter, width = 15, height = 15, units = "cm") 
```

Where .orange["peng_scatterplot.png"] is the name we want to give the new file & the image type we want it to be

- we can create many different file types (pdf, jpeg & so on..)

.orange[width =] & .orange[height =] allows us to specify the size of the image, measured in the .orange[units =] we've specified

The plot will be saved to your working directory (aka your R project) by default, or you can specify a file path

# Assignment .orange[<-]

To be able to specify the plot object we want to save with ggsave(), we have to give our plot a name .orange[<-]

For example:

```r
peng_scatter <- ggplot2::ggplot(peng_data, aes(bill_length_mm, bill_depth_mm, colour = species))

*peng_scatter <- peng_scatter +
  geom_point() +
  labs(title = "Scatterplot of Bill Length & Bill Depth", 
       x = "Bill Length (mm)", y = "Bill Depth (mm)") +
  theme_bw()
```

If you save your plot, and can't see any data points on it - just the grid, it is likely you have skipped out this assignment step

Just assign your plot like above, re-run the code, & re-run ggsave() to overwrite the image

# Inserting into Word

Inserting your exported plots into a Word doc is super simple

# Your Turn! 🥳

Practise using ggsave() with the examples in the [R Script](https://and.netlify.app/seminr/07/essentials/essentials_07.R)

<br>

Try using ggsave() to save your plot for the AnD assignment and insert it into your Word doc (make sure to switch to your report project)
