As a Bonus lets look at how to rename the column using Base R package. Hope you have enjoyed Dplyr version of renaming. Rename all the column name with pattern “e” as “E”. Orange_df = Orange %>% rename_all(funs(str_replace_all(., 'e', 'E'))) This is accomplished by using rename_all() function along with str_replace_all() Function as shown below. In our Example we will rename the Column which has “e” as “E” for all the occurrences. Renaming all the occurrences of a column which satisfies the specific pattern can be done using rename_all() function followed by pattern and followed by replacement character.

Rename all the occurrence of a column using rename_all() function Rename the column name “age” with “tree_life” Orange_df = Orange %>% rename_if(is.numeric, funs(str_replace(., 'age', 'tree_life'))) This is accomplished by using rename_if() function along with is.numeric() and str_replace() Function as shown below. In our Example we will rename the Column only if it is numeric. Renaming a specific column which satisfies certain condition can be done using rename_if() function. Rename a column with condition using rename_if() function in dplyr R: Rename the column name “Tree” with “Tree_Type” Orange_df = Orange %>% rename_at(vars(starts_with('T')),įuns(str_replace(., 'Tree', 'Tree_Type'))) This is accomplished by using rename_at() function along with str_replace() Function as shown below. uppercase: To convert to uppercase, the name of the dataframe along with the toupper is passed to the function which tells the function to convert the case to upper.

In our Example we will rename the Column that starts with “T”. Output: Method 2: Using renamewith() renamewith() is used to change the case of the column. Rename a specific column that starts with certain character. Lastly, we use select() from dplyr to both re-order and rename to nicer column. Rename like using rename_at() function dplyr R: This page demonstrates the use of janitor, dplyr, gtsummary, rstatix. Rename the column name “age” with “Life_of_tree” Orange_df = Orange %>% rename(Life_of_tree = age) rename() function takes following rename condition new_name = old_name. Rename the column name using rename function along with pipe operator in dplyr. # Rename multiple columns of the dataframe at once we will be passing the column names to be replaced in a vector as shown below. rename() function takes dataframe as argument followed by new_name = old_name. Renaming the multiple columns at once can be accomplished using rename() function. Rename Multiple column at once using rename() function: Rename the column name “age” with “Life_of_tree”. Orange_df = rename(Orange, Life_of_tree = age) # Rename the column name of the dataframe Apply the functions select(), rename() and mutate(). Rename the column name using rename function in dplyr. Use the dplyr package to manipulate tabular data (add or modify variables, select and rename columns). Rename the column name in R using rename() function : Select ‘Rename’ from the column header menu of the column you want to change the name.We will be using Orange data to depict the rename of column variable.
