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 <- "codemy"
string2 <- "Pro"
# using paste() to concatenate two strings
result = paste(string1, string2)
print(result)
Output
[1] "codemy 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 "codemy" 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 = "codemy"
string2 = "Pro"
# concatenate two strings using separator
result = paste(string1, string2, sep = "-")
print(result)
Output
[1] "codemy-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.
