R Program to Concatenate Two Strings

Example 1: Concatenate Strings in R

# create two strings
string1 <- "codes"
string2 <- "withpankaj"
 
# using paste() to concatenate two strings
result = paste(string1, string2)
 
print(result)
Output
[1] "codeswithpankaj"

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 "codes"and "withpankaj"

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 = "codeswithpankaj"
string2 = "p4n.in"
 
# concatenate two strings using separator
result = paste(string1, string2, sep = "-")
 
print(result)
Output
[1] "codeswithpankaj-p4n.in"

Here, we have passed the sep parameter inside the paste()

function to concatenate two strings: string1 and string2 with a hyphen in between them.
