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
with tubers and plants that grow in any other way.
