nls profiling with algorithm="port" may violate bounds (PR#8508)
...(but well-defined)
when the parameters are negative ...
As always, please don't hesitate to correct me
if I'm being an idiot ...

using minor tickmarks with xYplot
...o have but I don't seem to find any discussion on
the topic.
Following is one of the things I tried and the error returned:
xYplot(y~x,data.frame(x=seq(1,10),y=runif(10)),minor.ticks=c(3.5,5.5))
Error in panel(x = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), y =
c(0.88172451662831, :
object "gfun" not found
It's important that I use "xYplot" and not "plot" so function
minor.tick() is not useful.
Anything I can try? Thanks in advance for your help.

Maximum Likelihood Estimation
Using R, I would like to calculate algorithms to estimate coefficients á and â within the gamma function: f(costij)=((costij)^á)*exp(â*costij). I have its logarithmic diminishing line data (Logarithmic Diminishing Line Data Table) and have installed R¢s Maximum Likelihood Estimation package; however, I am unsure which method to apply in order to calculate the algorisms (i.e., Newton-Raphson

Grouping by factors in R
I'm having a hard time figuring out how to group results by certain
factors in R. I have data with the following headings:
[1] "Time" "Plot" "LatCat" "Elevation" "ElevCat"
"Aspect" "AspCat" "Slope"
[9] "SlopeCat" "Species" "SizeClass" "Stems"
