Select distinct rows by a selection of variables
Scoped verbs (_if
, _at
, _all
) have been superseded by the use of
across()
in an existing verb. See vignette("colwise")
for details.
These scoped variants of distinct()
extract distinct rows by a
selection of variables. Like distinct()
, you can modify the
variables before ordering with the .funs
argument.
distinct_all(.tbl, .funs = list(), ..., .keep_all = FALSE) distinct_at(.tbl, .vars, .funs = list(), ..., .keep_all = FALSE) distinct_if(.tbl, .predicate, .funs = list(), ..., .keep_all = FALSE)
.tbl |
A |
.funs |
A function |

.vars |

.predicate |
A predicate function to be applied to the columns
or a logical vector. The variables for which |
The grouping variables that are part of the selection are taken into account to determine distinct rows.
df <- tibble(x = rep(2:5, each = 2) / 2, y = rep(2:3, each = 4) / 2) distinct_all(df) # -> distinct(df, across()) distinct_at(df, vars(x,y)) # -> distinct(df, across(c(x, y))) distinct_if(df, is.numeric) # -> distinct(df, across(where(is.numeric))) # You can supply a function that will be applied before extracting the distinct values # The variables of the sorted tibble keep their original values. distinct_all(df, round) # -> distinct(df, across(everything(), round))
