How to split dataframe by text in a column with a function in R?

Question

I have a data frame that looks as below:

Name	ID1	ID2
M1	as	32
M1	ds	32
M1	sd	32
M1	ds	32
M1	sd	32
M1	sd	32
M2	sd	32
M2	gf	32
M2	gh	32
M2	hj	32
M2	kj	32
M2	kl	32
M2	uy	32
...	...	...
M100	yt	90

How do I split this data frame into separate data frames, each populated with rows containing M1, M2, M3....M100 individually, using a function?
