This won't answer the questions, but will point out that I wrote the
Nelder-Mead,
BFGS (I call it Variable Metric) and CG methods in BASIC in 1974. They were
re-coded
many times and then incorporated in R around 1995 as I recall (Brian Ripley did
the
incorporation). There are some great 50 year
Dear R-Users,
I am interested in the optimal strategy for optim:
Q: How to formulate the optimization problem?
Q1: Are there benefits for abs(f(x)) vs (f(x))^2?
Q2: Are there any limitations for using abs(...)?
Regarding point 1: my feeling is that the gradients should be more robust with
the a
Here is the skeleton of a function that lets you supply a function that
will be applied to diff(y) to say if this next point should be connected by
a line to the previous point.
p <- function (x, y = NULL, dy = diff(y), predicate = function(dy)
abs(dy)>2, ...,
xlab = if (!missing(x)) deparse1(su
It should be pretty easy to generalize my version of the `plot.gamma()`
function to a version of `curve()` with an extra `discontinuities` argument.

Dear Duncan,
Thank you very much for the response. I suspected that such an option has not
been implemented yet.
The plot was very cluttered due to those vertical lines. Fortunately, the gamma
function is easy to handle. But the feature remains on my wishlist as useful
more in general.

Dear R-Users,
Is there a way to skip over without plotting the jumps/discontinuities in

I have not seen such an option, but maybe I am missing something.
plot.gamma = function(xlim = c(-6, -1), ylim = c(-1,3), hline = NULL, n = 100

I think you should ask more from the BioC folks, or do more digging
yourself. At a minimum we would need to know what arguments were used
in the call that failed before we could help you with this. So if this
ever happens again, here's what you can do:
Run debug(install.packages), then the

Those three references are about RStudio and Bioconductor (or at least
they start out that way, I didn't read through the long threads).
Neither of those is relevant here, but from my quick scan it appears the
issue is that those systems detect a package in source form is
available, then ins
