It might not be random, depending upon a seed being used (usually by
set.seed or RNGkind).
However, it's the best method for generating a random number within a
specified range without weights.
If you want weights, there are many other random number generation
functions, most notably rnorm. You c
I saw runif(1) can generate a random num, is this the true random?

What's the other better method?
Thank you.

I am not sure your overall question fits into this forum but a brief
internet search can find plenty of info.
But in brief, R is a language in which much of what numpy does was built in
from the start and many things are vectorized. Much of what the python
pandas language does is also part of nati
This is dangerously close to off topic, or at least it could be fuel for
divisive argument rather than informed discussion (most readers here might be
short on details of NumPy and long on details regarding R).

Catherine,
R is a program that is designed for the statistical analysis and visual display
of data. Advantages and disadvantages depend on what you want to do with the
language.

I am familiar with python's Numpy.
Now I am looking into R language.

It seems like mysql server doesn't open the right authentication for your
access, such as user or host permissions.
Thanks.

I think we need the code you are running, any error messages you are
getting and some sample data. A handy way to supply sample data is to
use the dput() function. See ?dput. If you have a very large data set
then something like head(dput(myfile), 100) will likely supply enough
data for us to work

With no loops:

Dear Jim,
I restarted the mariadb.service but I am STILL not able to access the server.
I can access one database from one user but not from another user. The
credentials seem to be OK to me.
If I can figure this out I will post it here.
Many thanks,

Hi Ashim,
I was out for a while. I would first try to restart MySQL, then if
that didn't fix it, try logging in as root and accessing the database.
While I can't debug this at a distance, I'm pretty sure that the
database thinks that you aren't authorized to access it. If the
restart works, your pr
