My experiment is CRD: Two Factor Factorial Experiment, Fixed Effects. Factor 1: Levels: a,b (2) Factor 2: Levels: p,q,r (3) for each experimental units, there are four subsamples (Observational units) I want to add subsampling to this model and do the analysis, As I've referred this is only possible in GenStat S/W (http://www.stats.net.au/dropbox/ANOVA%20&%20REML%20manual.pdf Page 48). enter image description here How can I modify the R codes to get the above ANOVA output and mean separation?

stem_lengths <- c(3.5, 2.5, 3, 5, 3.5, 4.5, 5, 5.5, 5.5, 8.5, 6.5, 7, 6, 6, 6.5, 7, 6, 11, 4, 4.5, 3, 5.5, 3.5, 4, 4.5, 6, 4.5, 6, 7, 7, 5.5, 8.5, 6.5, 9, 7, 7, 3, 5.5, 2.5, 4, 3, 4, 5, 5, 6.5, 9, 8, 7, 3.5, 4.5, 8.5, 8.5, 7, 9, 4.5, 5, 3, 3.5, 4, 5, 4.5, 5, 5.5, 8.5, 6.5, 7, 7, 7.5, 7.5, 8.5, 7, 8)

 stems <- data.frame( temp = rep(rep(as.factor(c("high", "low")), each = 9), 4), daylight = rep(rep(as.factor(c(8, 12, 16)), each = 3), 8), pot = rep(as.factor(1:18), 4), len = stem_lengths )

aov.stem <- aov(len ~ temp * daylight, data = stems)  aov.stemsummary(aov.stem)coefficients(aov.stem)

Thanks Ram. no worries. I just thought to post this Q in here since it's related to Biological data analysis / Design experiments thinking that most of the experts in here are familiar with this type of Q.

Thanks. I'll post this CV.
