How to remove NA values ​​from csv file in RStudio?

Question

R

Imported csv file and opened it in RStudio. It says NA in several columns and rows. There should not be any values ​​in these cells. They are empty. But RStudio sees them and fills them with NA. Because of this, analysis does not occur. How to make it so that the program sees only those cells in which there are values, and those that are empty do not take into account at all?

Answer 1

put zero there instead of NA
