Spline interpolation

[Poko]

Hi All,

I am interporlating some missing values for a specific variable in R and when i do that, the interpolated variable is no longer part of my data set, i.e, i get only that interpolated variable.

So, how can i ensure that the interpolated variable becomes part of my dataset? Any sample code??

What have you tried so far? If you wrote code, but find it unsatisfactory, then please share that code so that it can be discussed.

Please provide a self-contained REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

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.…
