Calculation of lags
Hi,
If I have the follow situation:
A dependent variable (i.e. number of insects) that is affected by an
independent variable (i.e. rain). The problem is that the measure of rain
affect the population in other moment. So there exit a lag between the rain
and the number of insects. Exist in R any tool to find what is this lag?
Explain better.
Suppose that I have a linear relationship

xyplot source file only work with echo=TRUE
Hi,
I write several xyplot graphics on a source file. When I try to use
source("graphics.R") the source don't work, but if I use
source("graphics.R",echo=T) it work. Generally some commands work without
echo=T, but xyplot dont work. Why it dont work without echo=T? It is possible
to write a source that dont need echo=T on source command?

generating points over a function, its possible???
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
