I want to know if there is a way to rename column names by position of the column, rather than changing by column name.
Below snippet shows how to change by name.
suppressPackageStartupMessages(library(dplyr)) gd_url <- "http://tiny.cc/gapminder" gtbl <- gd_url %>% read.delim %>% tbl_df gtbl <- gtbl %>% rename(life_exp = lifeExp, gdp_percap = gdpPercap) gtbl

How to rename column by index in the R data frame? R provides base function colnames() and names() function to change column name by index position. Besides these, use dplyr rename() , select() and rename_with() to rename/change a DataFrame (data. frame) column.
To rename a column in R you can use the rename() function from dplyr. For example, if you want to rename the column “A” to “B”, again, you can run the following code: rename(dataframe, B = A) .
colnames() method in R is used to rename and replace the column names of the data frame in R. The columns of the data frame can be renamed by specifying the new column names as a vector. The new name replaces the corresponding old name of the column in the data frame.
rename() is the method available in the dplyr library which is used to change the multiple columns (column names) by name in the dataframe. The operator – %>% is used to load the renamed column names to the dataframe. At a time it will change single or multiple column names.
Much simpler: you can rename a column just by using numbers. This works:
df <- df %>% rename(newNameForFirstColumn = 1, newNameForSecondColumn = 2) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
