For example, an "o" with a German umlaut over it becomes "o", and the Spanish character "enye" becomes "n". Return Values: Returns the data.frame with clean names. Details: clean_names() is intended to be used on data.frames and data.frame like objects. For this reason there are methods to support using clean_names() on sf and tbl_graph (from tidygraph ) objects. I’ve also stuck with base R to limit dependencies. clean_names - function(.data, unique = FALSE) { n - if (is.data.frame(.data)) colnames(.data) else .data n - gsub("%+", "_pct_", n) n - gsub("\\$+", "_dollars_", n) n - gsub("\\++", "_plus_", n) n - gsub("-+", "_minus_", n) n - gsub("\\*+", "_star_", n) n - gsub("#+", "_cnt_", n) n - gsub("&+", "_and_", n) n - gsub("@+", "_at_", n) n - gsub("[^a-zA-Z0-9_]+", "_", n) n - gsub("([A-Z][a-z])", "_\\1", … We can run ‘clean_names’ function by selecting ‘Clean Column Names’ under ‘Others’ from the ‘Data Wrangling’ menu.
