Navigating the Jungle of R Packages
The R ecosystem has many packages in various collections,
especially CRAN, Bioconductor, and GitHub. While this
richness of choice speaks to the popularity and
importance of R, the large number of contributed packages
makes it difficult for users to find appropr
You are calling an optimizer that wants gradients without specifying the
gradient method. I've not done any work on
optimx for a couple of years -- on R-forge I've put optimrx which has a more
maintainable design and allows more solvers
to be called using the optim() syntax, including parameter s
Closely related to the different QR variations, Claudia Beleites and I
have a very crude start on some attempts to categorize different svd
approaches in R. Perhaps it's worth combining efforts with QR because of
the overlap and producing a sort of enlarged vignette or even a Task
View. I suggest c

In trying to rationalize some files in a package I'm working on, I
copied a function from one file to another, but forgot to change the

I noted that my nlmrt package on CRAN has package usl as a "reverse
imports". In a modest search I have yet to find a definition of the
term. Does anyone have a pointer?

There has been some disagreement on where it is appropriate to post
questions about package checking procedures, including the building of
the environment e.g., R-devel under Linux Mint.
In looking at https://www.r-project.org/mail.html, it seems to me that
the procedures belong with r-package-de

I have a general question about appropriate design for a fairly
complicated package, as I am redesigning and rebuilding the optimx
package. It will get a new name as it appears that the calls will change
in order to accommodate new functionality. I plan to make it
fairly easy to add new optimizatio
