Augmented design of meadowfoam

Description

Augmented design of meadowfoam

Usage

data("kling.augmented")

Format

A data frame with 68 observations on the following 7 variables.

plot

Plot number

gen

Genotype / Entry

name

Genotype name

block

Block, text

tsw

Thousand seed weight

row

Details

An experiment with meadowfoam. Blocks are in one direction, serpentine layout. There are 50 new genotypes and 3 checks (C1=Ross, C2=OMF183, C3=Starlight). New genotypes have 1 rep, checks have 6 reps. The response variable is thousand seed weight.

## Not run: 

library(agridat)
data(kling.augmented)
dat <- kling.augmented
libs(desplot,lattice,lme4)
# Layout and yields
desplot(dat, tsw ~ col*row, text=name, cex=1.5)

# Mixed model, fixed blocks, random genotypes
m1 <- lmer(tsw ~ block + (1|name), data=dat)
ran1 <- ranef(m1, condVar=TRUE)
ran1
dotplot(ran1) # Caterpillar plot
