[R] how to get the value of aov summary into another variable

Hi, I have a question of aov. e.g. aov.ex = aov(x~y) summary(aov.ex) The aov summary will print to the screen. How can I extract the aov result, in particular the values of Pr(F) and F value into a vector so that I can use them for other use? Thanks. -- Waverley @ Palo Alto

Dear Waverley, Try # Data x=rnorm(10) y=rep(1:2,5) aov.ex = aov(x~y) tail(unlist(summary(aov.ex)),2) # or anova(lm(x~y))$Pr(F) HTH, Jorge On Tue, Oct 28, 2008 at 8:48 PM, Waverley [EMAIL PROTECTED]wrote: Hi, I have a question of aov. e.g. aov.ex = aov(x~y) summary(aov.ex) The

Hello, R subscribers. I would like to define a function like this one: Fun - function(x)sin(x)/x with value 1 at x=0. How can I do that? Is there a way to plot it symbolically, without using x as a vector? e.g. x - seq(from=-10, to=10, length=100) plot(x, Fun(x)) Thank you in advance.

Re: [R] definition of a function

Dear George, Perhaps redefining Fn as Fun2 - function(x) ifelse(x==0,1,sin(x)/x) could help. Now, for the symbolic part (I'm not sure if understood correctly), try ?curve as follows: curve(Fun2(x),-10,10) HTH, Jorge On Wed, Oct 29, 2008 at 12:21 AM, KARAVASILIS GEORGE [EMAIL
