Usage

1

Format

A data frame with 8 observations on the following 8 variables.

testnam

a factor with levels Applied Test 1 Applied Test 2 Applied Test 3 Confirmation Test Query Applied Test 4 Applied Test Applied Test 5 Applied Test 6

Cultivar

a factor with levels Bogapple Chewton Pear (the names are invented)

X1

concentration (gm/cm$^3$) at 5 minutes

X2

concentration at 10 min

X3

concentration at 30 min

X4

concentration at 60 min

X5

concentration at 90 min

X6

concentration at 120 min

Details

Sortpion of fumigant by the fruit, different between different cultivars, is the main reason for the decline in concentration over time.
