Filtering Column by Multiple values

Question

I would like to filter values based on one column with multiple values.

For example, one data.frame has s&p 500 tickers, i have to pick 20 of them and associated closing prices. How to do it?

Answer 1

If I understand well you question, I believe you should do it with dplyr:

library(dplyr)
target <- c("Ticker1", "Ticker2", "Ticker3")
filter(df, Ticker %in% target)
