title: R: Error while recoding variables using car::recode function
body: <p>I frequently use 'recode' function in library(car) to recode levels in variables. My code was working fine up until today, but now it is throwing me error.
  Nothing's changed in df etc, not sure what's going on.
  <br>May be somebody could enlighten me!</p>
  
  <p><em>My Dataframe(sample)</em>:</p>
  
  <pre><code>test&lt;-structure(list(Avg.Salary = c("65000", "395", "82000", "128357", 
  "95785", "95785"), Education = c("Doctorate", "Professional Degree", 
  "Bachelor's", "Professional Degree", "Master's", "Master's"), 
  Count = c("D", "D", "D", "D", "D", "364584"), Year = c(2017, 
  2017, 2017, 2017, 2017, 2017)), row.names = c("540061", "540071", 
  "540081", "540091", "540102", "540112"), class = "data.frame")
