Here is what I did:
I switched to root in the MySQL Server, created a new user called
user2. I GRANTed user2 all permissions to access db2.
I create a matrix of size 3x3 called mat_1 and then I want to iterate over
all the values one by one and print the element as well as the position in
the matrix:
My code is :
mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol =
3,byrow = TRUE)
mat_1
# Loop over my_matrix
Dear Jim,
Can you please help me? I am a little confused here.
Best,
Ashim

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
mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol =
3,byrow = TRUE)
mat_1
# Loop over my_matrix
for(row in 1:nrow(mat_1)) {
for(col in 1:ncol(mat_1)) {
cat(row,col,mat_1[row,col],"\n")
}
}

Dear Jim,
Many thanks. I will try your suggestion and come back to you.

Hello,
With no loops:
cbind(
row = c(t(row(mat_1))),
col = c(t(col(mat_1))),
mat_1 = as.numeric(t(mat_1))
)
If the matrix entries are not numeric, use cbind.data.frame. This will
keep the row and column numbers as numbers, the default cbind method
would coerce them to the class of
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,
Ashim

Hi Anas,
How about:
cat(row,col,mat_1[row,col],"\n")

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 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

I am familiar with python's Numpy.
Now I am looking into R language.
What is the main difference between these two languages? including advantages
or disadvantages.
Thanks.

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

Perhaps also of interest:
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).
