I'm having trouble with the ordisurf function in the vegan package.
I have created an ordination plot (cmdscale) of 60 samples based on
Bray-Curtis dissimilarities, and would like to overlay various soil edaphic

Also, regular expressions try to match as early as possible. That's why
the match is at position one of length zero, and not at position four of

the optimization routine not to search at values in ( kappa = alpha ).
Also, you may find it helpful to pass the variable 'x' as part of the
function call (i.e. mll - function(param, x). This may avoid some
hard-to-diagnose errors.

Thanks Steve. This is working except for plots not showing up. I'll see
if I can fix that.
Do you know how to target the output to an R Console that will stay open
(Rgui would be best)?
Cheers,

Hi,
I need to be able to run an R script by double-clicking the file name in

Hi folks,
I am having trouble accessing sub-functions when the main function is
stored in an array. For example, the following test code works fine:
fcns = c(abs, sqrt)
fcns[[1]](-2)
fcns[[2]](2)
However, when I try to access sub-functions declared within list() in a
function, this only
that can have instances and class vars, without having to
use R's backwards (IMO) way of doing OOP.
Cheers.

Thanks, that was right (factor levels with no data). I forgot or
didn't know that when data gets changed, the factor levels don't get
changed as well. I'm sorry about missing parts of the Posting Guide.
