R Program to Concatenate Two Strings

Concatenate means joining multiple strings into one. In R, we use the paste() function to concatenate two or more strings.


Example 1: Concatenate Strings in R

# create two strings
string1 <- "Programiz"
string2 <- "Pro"
 
# using paste() to concatenate two strings
result = paste(string1, string2)
 
print(result)

Output

[1] "Programiz Pro"

In the above example, we have passed strings: string1 and string2 inside the paste() function to concatenate two strings.

The default separator in the paste() function is whitespace " ". So "Programiz" and "Pro" are joined with whitespace in between them.

We can specify our own separator by passing the sep parameter.


Example 2: Concatenate Strings Using a Separator

# create two strings
string1 = "Programiz"
string2 = "Pro"
 
# concatenate two strings using separator
result = paste(string1, string2, sep = "-")
 
print(result)

Output

[1] "Programiz-Pro"

Here, we have passed the sep parameter inside the paste() function to concatenate two strings: string1 and string2 with a hyphen in between them.
