I have created a data set and I am having some issues with graphing it. I think it stems from the fact that the data set is quite small so R doesn't recognise my X axis as years but rather as continuous data. Therefore, my graph has 2020.5. So, I have to convert the years column using `as.factor(AshQuads$Year)` but then it refuses to connect the years with `geom_line`.

This is the code I have been using

```
ggplot(Ash_Quads, aes(x=Year, y=Quadrats, colour=factor(Ash)))+
  geom_point()+
  theme_bw()

```

and this is my data frame: [![my_dataset](https://i.stack.imgur.com/xxPqo.jpg)](https://i.stack.imgur.com/xxPqo.jpg)

I was wondering if anyone can help please?
