How to Rename Variables within Columns in R (feat. case_when() code)?

How to Rename Variables within Columns in R (feat. case_when() code)?

In my previous post, I introduced how to change variable names within columns. In the post, I provided a simple code to rename variables and also used the stringr package for renaming variables. ■ How to Rename Variables within Columns in R? Today I’ll introduce another code to simply rename variables using dplyr() package. In my previous post, using the simple data above, I introduced how to rename variables. For example, we can rename variables using the below code. Or,…

How to change the name of columns in R?

Let’s upload one data to R. Now, I’d like to change the name of column as field → locationgenotype → varietyblock → repstreatment → experimentshoot → branchgrain_number → GNgrain_weight → GW I introduce two ways to change column names. 1) using colnames() 2) using rename() in dplyr package In this time, I’ll use dplyr package.

Stacking Data Vertically from Multiple Columns in R Studio (feat. reshape package)

Previously, I posted about how to change the data structure in the following scenario. □ Combining Factors from Separate Datasets into a Single Column Using R Studio (feat. dplyr package) This time, I will introduce a method for changing the structure of data as shown below. Specifically, this is about cases where there are multiple columns within a single dataset, not two different datasets. I will create a simple dataset for illustration purposes. This is a method for taking input…

Combining Factors from Separate Datasets into a Single Column Using R Studio (feat. dplyr package)

When data is divided into two separate datasets, it needs to be combined into a single column. Using R, we can simply combine the two datasets. I will create a simple dataset. Now I will combine these two datasets into one. 1) using data.frame() To explain the below code simply, we are using the function data.frame() to combine two datasets. Regarding the repetition of the text “Defoliation,” it indicates repeating it by the number of times corresponding to the values…
