Hi, I try to use a substitute function to generalise a equation. I have this: expression(1+2*pred+3*lat) I need to define the equation in function of x1 and x2 variables. Also I try to define who is x1 and x2. I try this: X1 <- "pred" X2 <- "lat" Now I need substitute pred and lat in equation by x1 and x2 defined on X1 and X2 above, I try this way: >

Hi, How to order the levels os factor not by alphabetic order but by mean of Y. Somethink like this: I have this alphabetic order: > levels(pH) [1] "alto" "baixo" "medio" the order by mean os yvar is: > sort(tapply(Riqueza,pH,mean)) baixo medio alto 11.56667 20.00000 26.80000 How to make the levels of pH ordered by this mean to the result to

Hi, I need to add some different curves to a each panel in a xyplot. I have a old function to make this using panel.number, like this: panel=function(x,y,panel.number,...){ panel.xyplot(x,y,...) if(panel.number==1){ panel.curve(-655.8689+769.1589*log(5)+64.7981*log(x)-206.4475*log(5)^2) } if(panel.number==2){

Hi, I have a new (for me) situation. I have a function for one linear model: y = 9.7909-0.035*x I have the variance of system var = 13.01403 Is possible to create a random vector points of Y (simulating the real data) over this curve using the function and the variance? I need this to a discipline. I have this: | \ | \ -> y = 9.7909-0.035*x and var = 13.014 | \ | \ | \ | \
