![]() To rename the column in R we can also use base functions in R instead of dplyr we can accomplish different renaming like renaming all the columns in R and rename the specific column in R. 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. Another way to rename columns in R is by using the rename () function in the dplyr package. 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. Often youll need to create some new variables or summaries, or maybe you just want to rename the variables or reorder the observations in order to make the. 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. In our Example we will rename the Column that starts with “T”. Rename a specific column that starts with certain character. Rename like using rename_at() function dplyr R: 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”. You can also use this method to rename dataframe column by index in R. ![]() At a time we can change single or multiple column names. The operator > is used to load the renamed column names to the data frame. Actually, colnames () is used to set or get the names of a dataframe. Rename DataFrame Column in R using rename () rename () is the method available in the dplyr package, which is used to change the particular column name present in the data frame. Orange_df = rename(Orange, Life_of_tree = age) Rename Columns From List Using colnames () colnames () is the method available in R which can be used to rename columns from the list (list with column names). # Rename the column name of the dataframe ![]() Rename the column name using rename function in dplyr. Rename the column name in R using rename() function : With my real data frame, I have many other necessary columns that can't be changed like this.We will be using Orange data to depict the rename of column variable. Let's say there was a mistake in my data and that all of my "green" attributes need to be "purple." Here's the bit of code I tried that was suggested over at the GIS StackExchange for a similar problem: df dfĪs you can see, it does indeed change my green attributes to purple.but also changes its corresponding number column. I can get pretty close to what I need, but I haven't been able to work around the way that my "solution" changes the data. I need help changing/renaming attributes within columns of a data frame in R. ![]()
