如何根据行名删除r中的一行

Question

If I have a dataframe and the rownames are words rather than numbers, how can I delete a specific row based on its name?

For example if a row name is "Bacteria", how can I delete only that row named "Bacteria"?

Answer 1

We can create a logical vector by making use of the comparison operator with row.names and use that row index to subset the rows. If df1 is the data.frame object name, then do

df1[row.names(df1) != "Bacteria", , drop = FALSE]
