Problem function

Good morning, I am new to R and I was trying to do a function that allows me to compare all the data of a row with a certain value that is at the end of the table and that varies for each row.
I have to check and count if each value of each row is greater than that number. The code I wrote is the following but I have no feedback on R
counter=0
for (i in 1:500){​​
for(j in 1:750){​​
if (db_class[j,i]>db_class[j,751]==TRUE) {​​
counter=counter+1}​​
i=i+1
}​​
j=j+1
}​​

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

In the spirit of the above guide, why not begin with imagining you have a simpler problem, like data that has smaller dimensions, something tangible like 3 cols by 3 rows. (as opposed to 500 x 751)

A B C D MEAN
4 3 6 7 5
2 4 5 8 4,75
4 6 7 9 6,5
5 7 6 1 4,75

If (A1 > Mean1) countrow1 = count1 +1...
if (B1>Mean1) countrow1= count1+1..

If (A2 > Mean1) countrow2= count2 +1...
if (B2>Mean1) countrow2= count2+1..
I need to create a new col that contain this count for every row
