如何在R中的小鼠多次插补后提取类mids数据中的特定列？

Question

I have 20% missing values in my dataset for some variables. after using the mice package in R (with m=5), I got 5 MI datasets as class mids data. I want to do further analysis (reduced rank regression which refers rrr form here) by using the MI datasets. how do I extract specific columns from the MI datasets as the response variable and predictors in my rrr model?

Answer 1

It looks like the rrr package requires two dataframes, one for of the predictor variables and one of the response variables.

You can use dplyr::select to select the column names you want to keep in both. If you are new to R, start with install.packages("dplyr") and library(dplyr).

Let me know if this works.
