Must write code in R. Use ANOVA to determine if a person's attitude(happy, sad, angry) has ANY EFFECT on their x mood ratio.

This is just my fake data. I just want to know how a factor that is string ( ex: "happy", "sad", "angry" not a numbers) that pair with a factor that is numbers (ex: 0.2, .5, .4) in R.

Maybe just use my fake small size example to do ANOVA. Also, I need an example statement of Ho and H from my fake data too. My real data is much larger size and completely different table, so please use my fake data as an example.

Fake Data:

	name	last_name	attitude	x1	x2	x3	x_mood_ratio
1	ama	c	sad	15	8	21	0.34
2	bma	a	happy	8	11	12	0.79
3	dma	c	sad	9	13	7	0.10
4	ema	b	angry	7	10	6	0.0
5	hma	b	happy	16	12	2	0.17
6	fma	e	happy	10	7	4	0.0
