Filtering a dataframe in R based on multiple Conditions

Question

I want to exclude specific participants from a DataFrame and create it from an existing DataFrame. I want a method to exclude it using multiple criteria. For example:- Excluding all men over 50 with low bp, I have tried subset() but it didn't worked for me.

Answer 1

Use this command:

df[!(df$gender == "men" & df$age > 50 & df$bp = "low"), ]

Just use this syntax to solve your problem.
