How to set the row names of a data frame passed on with the pipe %>% operator?

Question

I have a data frame which I am dcasting using the reshape2 package, and I would like to remove the first column and have it become the row names of

Answer 1

with the later version of tibble, a more elegant solution exists:

df <- df %>% pivot(.) %>% tibble::column_to_rownames('ID_full')

Answer 2

will this do?

iris %>% `rownames<-`(seq_len(nrow(iris)))

Answer 3

You can use the magrittr alias set_rownames:

df %>% set_rownames(.$ID_full)
