Dear R-Experts,
using both do.call(…) and Reduce(…), I wonder about the differences of both.

Elsa,
It is usual to write to package authors/maintainers about packages before
trying R-help. Inference for nonlinear quantile regression is still a bit
underdeveloped. To get logLik you can use:

Hi
I am using the package tables and want to have the rows in the numerical order

Hello,
First of all, there's no need for data.frame(cbind(...)). data.frame()
only will do the job, and it's less error prone.
As for the question, since the column Nodes is to become a factor, why
use as.character()? Without it the problem is solved:
data <- data.frame(Nodes,Values)

The order in the table is the order of the levels in the factor, so the
best thing to do is to set the order in the factor itself. You can do this
using the factor function when you create the factor, or with a function
like relevel after the function has been created. In your case, what

The Writing R Extensions guide has a good section on writing generic functions
and methods. However, has anyone generated any additional tutorials,

Perhaps showing additional examples of what works well and what risks to avoid.

Reduce will rbind 2 elements and then the result with the next element
of the list --- while do.call just applies rbind once on all elements of
the list at the same time.

Probably not. I would guess that most (or all) of us have no clue what
