## 小塩先生のspssでの分析例をやってみた。感謝
cond <- factor(rep(1:3, each=7))
result <- c(4,1,3,2,2,4,3,6,8,5,9,8,7,7,4,3,4,6,5,5,5)
aovres <- aov(result~cond)
TukeyHSD(aovres)
library(multcomp)
summary(glht(aovres, linfct=mcp(cond="Tukey")))
## TukeyHSDとglhtで微妙に結果が違うのはなんでだろーなー
## Dunnet 対照群は一番上の水準 ("a1")
summary(glht(aov(lmres),linfct=mcp(a= "Dunnett")))
## Williams なんだかよくわからない。水準間に順序が仮定できるときに使うらしい。
summary(glht(aov(lmres),linfct=mcp(a= "Williams")))
## そのうちやろう
# 2要因以上の分散分析で交互作用が出たときはプールされた分散をつかい統計量を算出する
# glhtの使い方。特にTukey
# 各群のサンプルサイズが違う場合の多重比較。
