grocerylist <- rename(weeds, coopers = "flowers", asahi = "species", vb = "soil", littlecreatures = "weeds") For demonstrating purposes, I am going to rename all the columns of weeds to nonsensical crap. If you want to rename multiple columns, this is a pretty simple addition. # Again, if you run this by itself it will not save to your data frame, unless you direct it to your data frame variable using the <.
# In the brackets we need to specify our data frame (weeds) followed by a second argument specifying the name we want for our column = the name we already have. rename() function from dplyr takes a syntax rename(newcolumnname oldcolumnname) to change the column from old to a new name. To do this with dplyr (a tidyverse package) we simply use the following command: weeds <- rename(weeds, flowers = flowers.m3) The second variable of the data frame is 'Latest Name' and I want to change it to 'Name'.
Trust me, when you spend an hour trying to fix a line of code only to find a single capital letter is missing, you will understand. I want to rename a column but, after running the code without errors, it doesn't change. Personally, this is my favourite function in R as I hate captials, fullstops and other annoying column name problems that slow down coding or generate errors. The rename() function allows us to simply rename a column name within our data frame. This will happen ALOT with data you enter or obtain from others, as R converts any spaces to fullstops and people tend to capitilise most words.
