R code of this tutorial:


data ＜- data.frame(x1 = c(3, 7, 1, 8, 5), # Create example data
x2 = letters[1:5],
group = c("g1", "g2", "g1", "g3", "g1"))

##### Example 1
data[data$group == "g1", ] # Subset rows with ==

##### Example 2
data[data$group != "g1", ] # Subset rows with !=

##### Example 3
data[data$group %in% c("g1", "g3"), ] # Subset rows with %in%

##### Example 4
subset(data, group == "g1") # Apply subset function

##### Example 5
install.packages("dplyr") # Install dplyr package
library("dplyr") # Load dplyr package
filter(data, group == "g1") # Apply filter function
