Usage

# S3 method for class 'igraph.vs'
unique(x, incomparables = FALSE, ...)

Arguments

x

A vertex sequence.

incomparables

a vector of values that cannot be compared. Passed to base function duplicated. See details there.

...

Passed to base function duplicated().

Value

A vertex sequence with the duplicate vertices removed.

Examples

g <- make_(ring(10), with_vertex_(name = LETTERS[1:10]))
V(g)[1, 1:5, 1:10, 5:10]
#> + 22/10 vertices, named, from ebac1c5:
#>  [1] A A B C D E A B C D E F G H I J E F G H I J
V(g)[1, 1:5, 1:10, 5:10] %>% unique()
#> + 10/10 vertices, named, from ebac1c5:
#>  [1] A B C D E F G H I J
