Answer / Ziaur Rahman
In R, you can use the `aggregate()` function to calculate the mean of a specific column with respect to another. Here's an example: `aggregate(column1 ~ column2, dataframe_name, mean)`, where `column1` is the column for which you want the mean, `column2` is the grouping variable, and `dataframe_name` is the name of your dataframe.
