Function to read multiple columns automatically

[Swincine]

Hi guys,

I have 6 columns ( 3 columns with text data, 3 more columns with numeric data ) in a data frame I need to read 3 columns (which is numeric) for now and when extra column added (numeric data) to the file dynamically my code has to read that column

How can I do that ?

Hi,

I do not understand what it is you are trying to do exactly. If you have the 6 columns already in a data frame, what do you mean by dynamically reading the data?

Please provide a reprex of your issue. A reprex consists of the minimal code and data needed to recreate the issue/question you're having. You can find instructions how to build and share one here:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.2…

Good luck,

load your data.frame with all its columns both char and numeric
use dplyr to select only the numeric ones

library(dplyr)
select(iris,
       where(is.numeric))
