Changing the rownames of a dataframe

Question

I have a dataframe t1 which has two fields names and rollno. I want to generate a data frame where the rownames are names. How can I do this in R?

Answer 1

You could do something like that:

a <- data.frame(name=c("A", "B"), b=1:2)
b <- data.frame(a=1:2, b=1:2)
row.names(b) <- a$name
