A data frame with 18 observations on 8 variables:
|[ , "V1"]||factor||winters|
|[ , "V2"]||factor||shadow|
|[ , "V3"]||factor||tubers|
|[ , "V4"]||factor||color|
|[ , "V5"]||ordered||soil|
|[ , "V6"]||ordered||preference|
|[ , "V7"]||numeric||height|
|[ , "V8"]||numeric||distance|
winters, is binary and indicates whether the plant may be left in the garden when it freezes.
