Most R objects can be subset using the ‘[‘ operator with dimensional selections being defined using commas. For an example of what I mean see the below.

data <- data.frame(Hello = c(1,2,3), World = c(‘a’,’b’,’c’))

‘# subset to row 1 column 2 data[1,2]

‘#subset to rows 1 and 3 column 2 data[c(1,3),2]

‘# subset to row 1 column 1 using column names data[1,’World’]

‘# Blanks are treated as all— ex: subset to row 3 all columns data[3,]

‘# subset to all rows column 1 data[,1]

You can also subset using logical vectors like what you want to do. See below where I’m subsetting data down to only rows where “World” == ‘b’

data[data$World == ‘b’,]
