How to filter data by many years
So I have a data that has many rows of country, year, and number of reported cases of cholera of that year. How should I go about filtering the data in ranges of years?
So I want data between 2008 - 2016 for example. For all I know, filter(__) seems only to do one year.
Also, how should I go about filtering for certain names in variables? So lets say I have a few rows that say X, Y, Z, C, D. How do I only filter for rows of "X" "Y" Z" for example?

between() and %in% are the operators you're looking for. To filter on both of your criteria simultaneously:
library(dplyr)
filtered_data <- (your_data %>%
filter(between(year,2008,2016),
interesting_row %in% c("X","Y","Z"))
)
Note that between(year,2008,2016) is (nearly) equivalent to 2008 <= year & year <= 2016
