dplyr (version 0.5.0)

filter: Return rows with matching conditions.

Description

Return rows with matching conditions.

Usage

filter(.data, ...)
filter_(.data, ..., .dots)

Arguments

.data

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

...

Logical predicates. Multiple conditions are combined with &.

.dots

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

Value

An object of the same class as .data.

Data frame row names are silently dropped. To preserve, convert to an explicit variable.

# Multiple criteria

# Multiple arguments are equivalent to and
filter(mtcars, cyl < 6, vs == 1)
