Hello everyone, I'm not used to using StackOverflow in terms of asking questions, but I have used it to find solutions to problems I've had in the past. I'm currently taking an advanced programming class involving the use of the language "R". In problem 20 (shown in the picture above), I was tasked to filter out the students in df20 who have a GPA higher than 3.0 and put them into a new dataframe named "df20a" I was able to create the dataframe and reassign a value to a student shown in the example, but I am having trouble with the final steps. If anyone is able to help me with this solution and provide an explanation on how to achieve the result im looking for, It'd be much appreciated.
Thank you for your time & I hope you're having a wonderful and blessed day!
