Extract two rows out of dataframe - r

Question

How can I extract two rows (rows a and b below) from my data frame df?

df1 = df[(df$column1 == "a" & "b"),]

or `df1 <- subset(df, column1 %in% c("a", "b"))` or `df1 <- dplyr::filter(df, column1 %in% c("a", "b"))` — Maurits Evers, Jun 06 '18 at 13:10
Are `"a"` and `"b"` values in `column1` or are they row names? If the latter, you can do `df[c("a","b"),]` — Andrew Gustar, Jun 06 '18 at 13:15

Just use the subset function: subset(df, subset = column1 %in% c("a","b"))
