Paste Utilities – Concatenate Strings

Concatenate vector elements or anything using paste(*, collapse = .). These are simple short abbreviations I have been using in my own codes in many places.

Usage

vcat(vec, sep = " ")
ccat(...)

Arguments

vec, ...

any vector and other arguments to be pasted to together.

sep

the separator to use, see the Details section.

Details

The functions are really just defined as

 vcat :=  function(vec, sep = " ") paste(vec, collapse = sep)
 ccat :=  function(...)           paste0(..., collapse = "")

Value

a character string (of length 1) with the concatenated arguments.

Examples

ch <- "is"
ccat("This ", ch, " it: ", 100, "%")
#> [1] "This is it: 100%"
vv <- c(1,pi, 20.4)
vcat(vv)
#> [1] "1 3.14159265358979 20.4"
vcat(vv, sep = ", ")
#> [1] "1, 3.14159265358979, 20.4"
