inspect_map {cleandata}  R Documentation 
Provide a map for imputation and encoding.
inspect_map(x, common = 0, message = TRUE)
x 
The data frame 
common 
a nonnegative numerical parameter, if 2 factorial columns share more than 'common' levels, they share the same scheme. 0 means all the levels should be the same for 2 factorial columns to share the same scheme. 
message 
Whether print the process. 
A list of factor_cols

(vector).

a list, in which each member is a vector of the names of the factorial columns that share the same scheme. The name of a vector is the same as its 1st member. Refer to the argument
