Convert 'haven labelled' to factor.

[Nile]

Hi,

I have a df imported from Stata using the haven package which is automatically changing the types of columns to "haven_labelled" as shown below. There are about 980 columns in total, and I want to convert them to factors while preserving the labels e.g. yes/no.

I tried the as.factor(df) command, but it is not working.

> class(df$smoke)
[1] "haven_labelled"
[2] "vctrs_vctr"    
[3] "double"

Please suggest to me if you know of any method to do this.

Thank you in advance!

haven library contains as_factor function that probably does what you want.
If not / not quite. Then please consider providing a reprex.

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.…
