You'll need to send a reproducible example of the code. We can't run the
code that you send. Hence it is hard to help you. See e.g.

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.

>>> Dear list members,
>>>
>>> I have a loop where I want to do several calculations for different
>>> samples
>>> and save the results for each sample. These samples are for each loop
>>> different. I want to use the "i" in the loop to cut the samples.
>>>
>>> So for instance:
>>>
>>> - In loop 1 (i=1), I have a sample from 0-1 and a sample from 1-100.
>>> - In loop 2 (i=2), I have a sample from 0-2 and a sample from 2-100.
>>> - In loop 99 (i=99), I have a sample from 0-99 and a sample from
>>> 99-100.
>>>
>>> I built the following function, but there is *a problem with the cut2
>>> function* since it doesn't recognize the "i". Outside the lapply loop it
>>> works, but not inside the loop.
