I am trying to reproduce an analysis done in SAS from which Type III Sums of squares are used. How can you get Type III sums of squares in an aov similar to what SAS provides?

Hello This is a very newbie question on R syntax, but I do not find the answer.... I want to make a selection on an interval say choose Xint in the interval of temperatures 390-399 I tried this syntax Xint<- X[t>=390 && t< 400] typing >XintI get the answer numeric(0) it did not select any object!

Hi all, I have some (stupid) problems to display results and i don't find a solution. 1- res<-c(1,2,3) I would like to display >Results are 1 2 3 The following command cat(paste("Results are ",res,"\n")) give me >my results are 1 my results are 2 my results are 3 2- res<-cbind(c(1,2),c(2,3)) I would like to display >Result is the matrix 1 2

I'm sure this is a total noob question, but half an hour of searching bore no fruit: How do you select a subset of a vector by negative value? If I try > hist(sp$p[sp$r>0.01]) # all is well > hist(sp$p[sp$r<-0.01]) # this obviously causes issues Also, putting -0.01 in parentheses didn't help. Thanks in advance -- b

Is there a function in R, which would return index of maximum value in a vector ? e.g. > v <- round(10*rnorm(8)) > v [1] 6 -3 -6 15 7 9 0 -19 > max(v) [1] 15 ??? index.max(v) ??? 4
