Question

How to filter only those rows with a condition in R? I need to only show students that have taken subject code 001 and having marks greater than 80 for the subject. I need to show a plot of number of students vs total students.

Answer 1

Write R code as below

temp = data %>% filter(subject code == "001",marks >80)

Filter() in dplyr is used to filter the data using a condition check.

The above dataset will contain data that satisfy the condition.
