The way to do what you want is to use the split function, for
example,
mydataframes = split(exmpl,exmpl$Site)
This will return a list with all the data frames.
If you don't understand why this is a better solution than
creating many separate data frames, let us know what you plan
to do with the data frames you're creating.

I would like to create a certain number of dataframes out of one dataframe
where each of the dataframes
is related to a factor. This should be possible with a loop or a function,
as is very clumsy to do it manually
when there are quite a lot factors.
For example having a dataframe called "exmpl":
Site Value
1 12
1 15
1 18
1 21
1 12
1 13
2 15
2 12
2 58
2 62
2 22
2 65
2 29
3 21
3 55
3 11
3 98
I would like to create 3 dataframes, where
"exmpl_01" equals:
1 12
1 15
1 18
1 21
1 12
1 13
"exmpl_02" equals:
2 15
2 12
2 58
2 62
2 22
2 65
2 29
"exmpl_03" equals:
3 21
3 55
3 11
3 98
Thanks for any help.
