Hello everyone. I am a beginner R user. I need help with finding the percentage of column F to column E for row 255. The data is a total of 2113 rows. How do I go about doing this?
We need some sample data and I think more explanation of what you are doing.
and you might find this useful
If you wanted just row 255:
df[255, "ColumnF"] / df[255, "ColumnE"]
If you want the percentage for all rows:
df$ColumnPercent <- df$ColumnF / df$ColumnE
Hope this helps.
