Data Engineering and BI courses are free this week!
This function launches a shiny app in a web browser in order to do interactive reordering of the levels of a categorical variable (character or factor).
iorder(obj = NULL, var_name = NULL)vector to recode or data frame to operate on
if obj is a data frame, name of the column to be recoded, as a character string (possibly without quotes)
The function launches a shiny app in the system web browser. The reordering code is returned in the console when the app is closed with the "Done" button.
The generated convert the variable into a factor, as only those allow for levels ordering.
data(hdv2003)
iorder(hdv2003, "qualif")
Run the code above in your browser using DataLab
