Hi, 

Use print function print(Anova(...))

How about use of lappy functions ? It can be much easier

foo<-function(data,formula){
     LM <- lm(formula,data=data)
    Result<-list(LmSum<-summary(LM), Type2<-Anova(LM, type="II")),Type3<-Anova(LM, type="III"))
}

and print(lappy(split(data,year),foo,formula=...))

Objet : [R]  problems with for loop

Hello,

With this program I try to repeat analysis for different years. The
results of the analysis are not printed when in the loop, except for the
year sequence. What is wrong?

Thanks a lot.

for (i in 92:99){
    cat("\n",
    "=============================================================\n",
    "YEAR =",i,"\n",
    "=============================================================\n"
    )
    canos1 <- subset (canos, canos$YEAR==i)
    LinearModel.1 <- lm(MM_P  ~ BLOC  + TIL, data=canos1)
    summary(LinearModel.1)
    Anova(LinearModel.1, type="II")
    Anova(LinearModel.1, type="III")

}
