In this article, you have learned how to rename file names in R by using file.rename() and rename.files() functions. The following is a complete example of how to change file names in R. ![]() For example, changing the file name from file_name.txt to file-name.txt. The below examples change file names that have a text _ (underscore) to – (hyphen). 2.2 Rename File Names in a Directoryīy using the rename.files() function let’s see how to rename all files that match the pattern in a directory. replacement: Replacement text when a pattern match.pattern: Pattern to look for file names in a directory.dir: Path to the directory where you wanted to change file names.The following is the syntax of the rename.files() function. You need to check the directory if the changes to the names have applied as expected. This function prints Done! to the console after renaming all files. The rename.files() function in R is used to rename all file names recursively from a directory by using a regex expression. rename.files() – Uses Regex to Rename File Names Here, the c() function is used to create a Vector. It changes the file name element-wise, the first element from vector to the first element on to vector.įrom_files <- c('file_name1.txt','file_name2.txt','file_name3.txt') Note that if you try to rename a file that doesn’t exist, it returns a warning message “cannot rename file ‘file_name.csv’ to ‘file-name.csv’, reason ‘No such file or directory'” hence, you need to check if file exists using a file.exists() function.īy using the same function you can change multiple file names, To do so you need to specify the vectors for from and to params. The following example first checks if the CSV file exists using file.exists(), when the file exists it renames from file_name.csv to file-name.csv. 1.2 Rename Single File Nameīy specifying the text value to from and to params you can rename a single file name. ![]() The following is the syntax of the file.rename() function. ![]() Use file.rename() function to rename a file name in R programmatically, by using this you can either change a single file name or change multiple file names at a time by specifying from and to params as vectors.
