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=...))

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")

}
