Thanks for the help guys. Sorry, I will not post further RStudio questions
here. Yihui, thanks for the tip. Looks like these commands would do:

encoding='UTF-8')

Dear All:
I have
v = c(xy, xy^2, z)
dotv = sum(v*v)
I hope, I have the following result:
dotv = x^2*y^2 + x^2*y^4 + z^2 (still in variable x, y and z, not
numeric result)
How to make simple script, so that I have: dotv = x^2*y^2 + x^2*y^4 + z^2
Thanks a lot for your help.
Best regards,
Yes, that is pretty much it. Setting the options useDingbats or
concordance is optional. You may or may not really need them. What is
essential is the knit() function.
Regards,
Yihui

Hi,
With the 'merge' function using different tolerance level, I've come up with a
solution.
For e.g. consider r1 and r2 as two raster layers, attributes are as follows:
r1 - raster(xmx=-150, ymn=60, ncols=30, nrows=20)
r1[]-1:ncell(r1)
r1

I have selected a small code to show you exactly the problem

A wild guess -- take a look at the CRAN phylohenetics task view, as

It sounds like you will need to use logistic regression. Although the following
