writing simple function through script
...cript, when I call the function yo on data
called NC60.DATA I get an error.
#yo(NC60.DATA)
Erreur dans eval(expr, envir, enclos) : objet "Xdata" not found
The object Xdata isn't found. Why?
Is that possible to debug a function with R?

ggplot bar geom: control the filling in the colour legend
Hi all,
Is it possible to change the filling of the squares used to represent
the colour legend in a bar plot with ggplot?
in this example, fillings are raven black, I'd like them white.
ggplot(diamonds, aes(clarity, colour = cut)) + geom_bar()
Regards

ggplot2: geom_smooth and legend
...i all,
Is that possible to remove the grey colour in the legend key that goes
with the geom_smooth? In my case it doesn't ease the reading of the
legend.

axis text size in scatter plot
Hi,
Quite simple question I guess.
Where could we specify the size of the text (axis,legend) for a scatter plot
graphic made with plot()?

superscript text style in axis label in graph
Hi all,
I'd like to use superscript or subscript in the axis label of a graph. Is
that possible in R?
For instance in xlab="Ce (mmol/m3)", I'd need the "3" of cubic meter in
superscript.
Regards/Cordialement

continue a loop after an error with confint
...foo<-list(foo,confint(Reg3Lst[[i]]))
}
For some regressions the confidence interval is not estimated because of a
singular gradient result. Then it stops the loop.
Is that possible to continue the loop after an error returned by confint?

curve from a formula with ggplot2
...ccording to a specific formula
like
y = a*(b*x^n)/(1+b*x^p)
where a,b,n and p are known parameters.
I guess it's possible and easy to add this layer with ggplot, somehow I
didn't find the right function.
Any help would be warmly appreciated.

parameter assessment in differential equation
...K1 * (qm-x)*C - K2x
where {K1,K2} are the unknown paramters and {qm,C} are known parameters
Of course I get experimental data sets of measured x as a function of time.
If R can help to handle that, which functions have to be used (diff, optim,
nls...)

grid lines aligned on each ticks with a log scale
...t(seq(1,9), log="x", panel.first=grid())
how to get lines at x = 2 and 5 on the graph?
Of course the option "nx" in grid() is not valid, as it does not align the

Thanks for giving a hand.
