Collapse a character vector

Source: R/glue.R, R/sql.R

glue_collapse() collapses a character vector of any length into a length 1 vector. glue_sql_collapse() does the same but returns a [DBI::SQL()] object rather than a glue object.

glue_collapse(x, sep = "", width = Inf, last = "")

glue_sql_collapse(x, sep = "", width = Inf, last = "")

Arguments

x

The character vector to collapse.

sep

a character string to separate the terms. Not NA_character_.

width

The maximum string width before truncating with ....

last

String used to separate the last two items if x has at least 2 items.

Value

Always returns a length-1 glue object, as created by as_glue().

Examples

glue_collapse(glue("{1:10}"))
#> 12345678910

# Wide values can be truncated
glue_collapse(glue("{1:10}"), width = 5)
#> 12...

glue_collapse(1:4, ", ", last = " and ")
#> 1, 2, 3 and 4
