Usage
data(flower)
Format
A data frame with 18 observations on 8 variables:
[ , 1] | factor | winters |
[ , 2] | factor | shadow |
[ , 3] | factor | tubers |
[ , 4] | factor | color |
[ , 5] | ordered | soil |
[ , 6] | ordered | preference |
[ , 7] | numeric | height |
[ , 8] | numeric | distance |
- winters
- is binary and indicates whether the plant may be left
in the garden when it freezes.
- shadow
- is binary and shows whether the plant needs to stand
in the shadow.
- tubers
- is asymmetric binary and distinguishes between plants

(1), normal (2), or wet (3) soil.
- preference
- is ordinal and gives someone's preference ranking
going from 1 to 18.
