Select rows by position.

Slice does not work with relational databases because they have no intrinsic notion of row order. If you want to perform the equivalent operation, use filter() and row_number().

slice(.data, ...)

slice_(.data, ..., .dots)


A tbl. All main verbs are S3 generics and provide methods for tbl_df, tbl_dt and tbl_sql.


Integer row values


Used to work around non-standard evaluation. See vignette("nse") for details.

For many databases, you'll # need to supply an explicit variable to use to compute the row number. filter(mtcars, row_number() == 1L) filter(mtcars, row_number() == n()) filter(mtcars, between(row_number(), 5, n()))
