# R paste() Function - String Concatenation [ R Language Examples](https://example.com/r/r-examples.html) The R paste() function is used to concatenate multiple strings or vectors together. paste0() is a separator-free version of paste(), equivalent to paste(sep = ""). The paste() function syntax is as follows: paste(..., sep = " ", collapse = NULL) paste0(..., collapse = NULL) **Parameter Description:** * **...** Strings or vectors to concatenate. * **sep** Separator during concatenation, default is a single space. * **collapse** Further merges the concatenated vector into a single string, using collapse as the separator. ## Examples # Basic concatenation (default space separator) result1 <-paste("Hello", "TUTORIAL", "R") print(result1) # Specify separator result2 <-paste("2026", "05", "11", sep ="-") print(result2) # paste0 without separator result3 <- paste0("ID_", 1:5) print(result3) # Use collapse to merge vector into a single string words <-c("R", "is", "powerful") sentence <-paste(words, collapse =" ") print(sentence) Executing the above code outputs: "Hello TUTORIAL R" "2026-05-11" "ID_1" "ID_2" "ID_3" "ID_4" "ID_5" "R is powerful" paste() is commonly used to dynamically generate labels or filenames: ## Examples # Generate month labels months<-paste("Month", 1:12, sep ="") print(months[1:5]) # Generate file paths path <- paste0("data/", c("sales", "inventory", "customers"), ".csv") print(path) Executing the above code outputs: "Month1" "Month2" "Month3" "Month4" "Month5" "data/sales.csv" "data/inventory.csv" "data/customers.csv" [ R Language Examples](https://example.com/r/r-examples.html)
