...the regression between the two variables usign the command lm(A ~ B, ...) but now I want to know the regression coefficient (r2) of A vs. B for every factors. I know that I can obtain this information with excel, but the factor have 68 levels...maybe [r] have a useful command. Thanks, Francesco Nutini [[alternative HTML version deleted]]

...s, I need to produce a histogram where for every breaks there are the mean of the data. I tried tu use the function >hist(x, break=20 ... ) but this return the numerosity for every breaks, not the mean. Any hint?

...want: | | | | |_|_|_| I tried to use the command "par", but it's doesn't work with xyplot. The two plot have, by default, the same x-axis scale. I know it's just a "visual solution", but it could be nice for a paper! Thanks a lot, Francesco Nutini PhD student [[alternative HTML version deleted]]

Dear R-Users, I'd like to have some tips about printing graph. I use the command par to print more graphs in one window:par(mfrow=c(6,1)); par(oma=c(2.5, 2.5, 2.5, 2.5)); par(mar=c(0.5,4, 0.5, 0.5)) But this command doesn't run with complex graphic command (i.e. xyplot, ternaryplot).How can I print more than one graph per page, when I work with this "elaborated" graph?Many

Dear R-Users, I'd like to have your help on this problem: I have two vectors:x<- c(0,1,0,0,0,0,0,0,0,0,0,1,0)y<- c(0,0,-10,0,0,-10,0,-10,0,0,0,0,0) And I want to know where the value -500 in y have a correspondence value 1 in x.Considering a buffer of one position before and after in x.i.e. in this example only the -10 in position y[3] satisfies the criteria, because x has in position

...ct?" I have the same problem about the interpretation of command "summary", and generically about the finest post-hoc test for implemented model with the code "lm()". I think that R-help is quite insufficient... Which command did you use normally? Thanks a lot, Francesco Nutini

Dear R-Users, I'd like to have some tips for a ternaryplot ("vcd").
