dataframe with 22 variables

Hi there, new guy on the site. :) How do I convert these 22 variables into 5 explanatory variables with levels instead of the current boolean using Rstudio? I’ve tried a few different approaches, but I cannot get it to work properly.

  • Not clear about what you wanted. it is better to show a small example along with expected output instead of images – akrun Nov 01 '18 at 18:02
  • fx, the BuyingPrice columns I would like to combine into a single column so I get a factor BuyingPrice: low (1), medium (2), high (4), and very high (5) to perform a log reg on the data to predict the Evaluation (acceptable or unacceptable) of the car based on 5 explanatory variables. – Christopher Clark Nov 01 '18 at 18:06

Welcome to SO! have you tried as.factor?

> as.factor(c(1,0))
[1] 1 0
Levels: 0 1

Say you want to convert columns 2:6 in your df then:

df[,2:6] <- as.factor(df[,2:6])
