Usage

fumig

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
