How to select some rows with specific rownames from a dataframe? [closed]

r dataframe subset rowname

Assuming that you have a data frame called students, you can select individual rows or columns using the bracket syntax, like this:

If you'd like to select multiple rows or columns, use a list of values, like this:

Hope I could help.

r dataframe subset rowname

You can also use this:

DF[paste0("stu",c(2,3,5,9)), ]

r dataframe subset rowname

df <- data.frame(x=rnorm(10), y=rnorm(10))rownames(df) <-  letters[1:10]df[c('a','b'),]
