plot(x=population, y= CO2, data = year15)

plot(x=carb, y=CO2, data = year15)

plot(x=gdppc, y=CO2, data = year15)

Error in xy.coords(x, y, xlabel, ylabel, log) :

'x' and 'y' lengths differ

how do i fix this error?

I notice that there is no column named CO2 in year15. There is one named co2. Try changing your plot commands to commands like

```
plot(x=population, y= co2, data = year15)
```

If that does not fix the problem, please run

```
dput(head(year15, 30))
```

and post the output here. Put a line with three back ticks just before and after the pasted output, like this

```

Pasted output goes here
