Re: [R] tidying up
Hi Avi, I thought about your question over the past few days. A new email list may help, but I doubt the help will suffice to solve the problem of forming emails as the existing list prefers. Here is where I see the source of the problem with using R by way of getting questions answers. https://cran.r-project.org/doc/manuals/r-release/R-intro.html This writing is not an introductory learning piece. This work needs to be restructured and expanded. It is evident another author would need to be found who has the writing skills to accomplish the necessary improvements. *Stephen Dawson, DSL* /Executive Strategy Consultant/ Business & Technology +1 (865) 804-3454 http://www.shdawson.com On 2/27/22 16:59, Avi Gross via R-help wrote: Indeed, Jim, the hopeful purpose of interactions here is to help people without doing the job for them.

Re: [R] tidying up
FWIW my brief answer to your brief question is "of course" it is okay. The real problem however are the questions that can only be answered by people with detailed understanding of non-R-related issues, such as the workings of the custom interactive graphics device used by RStudio or the broken behavior of some random GitHub-hosted package. There are a continuum of possible "degrees of relevance" that a question can have to the topic of a given discussion area (e.g. web forum or mailing list). The people who don't use RStudio don't gain benefit from wading through discussions that only have relevance to that tangential topic, and the more of that there is the lower the signal-to-noise ratio is from their perspective... and the sooner they leave. Ideally we will be kind in our redirection of the uninitiated, but an actual answer may not be feasible here... going elsewhere for a specific question should not be viewed as a negative outcome. Since there are various interpretations of where the line should be drawn, it is best that it be drawn as the discussion area charter says it should... in this case, about R, the language. It is pretty explicit that discussion of contributed packages is not on-topic... presumably because allowing that can easily lead to highly arcane discussions that don't necessarily help people understand the R language better. I think the existence of contributed packages and various development tools is hugely beneficial and I depend on many of them... but that doesn't automatically give any of them carte blanche to become actual topics of discussion here.

source(myfuns..R)
dump(ls(all = TRUE), file = new.myfuns.R)
I have done this for my own packages and although it runs, I get several
warnings of the type:
Warning message:
In dump(ls(all = TRUE), file = PermAlgo.R) : deparse may be incomplete
I am clueless as to what this means.
Even if I try to tidy only one function from my code, I get the warning.
E.g. the file lala.R contains only this:
partialHazards - function(t, v, covArray, betas){ exp( covArray[v,t,]
%*% betas ) }
the file tidylala.R contains:
options(keep.source = FALSE)
source(lala.R)
dump(ls(all = TRUE), file = newlala.R)
On Linux I run:
R --vanilla tidylala.R
Then I obtain:
Warning message:
In dump(ls(all = TRUE), file = newlala.R) : deparse may be incomplete
The file newlala.R looks like this:
`partialHazards` -
function (t, v, covArray, betas)
{
exp(covArray[v, t, ] %*% betas)
}
What does the warning mean? Can I simply ignore it?
thanks,

Dear R users,
I am currently writing a R package and to do so I am following the
guidelines in manual 'Writing R extensions'.
In Section 3.1, it is suggested to tidy up the code using a file
containing the following:
options(keep.source = FALSE)
source(myfuns..R)
dump(ls(all = TRUE), file = new.myfuns.R)

The warning means that you may have lost some information, i.e. sourcing
newlala.R won't produce the same thing as sourcing lala.R. I think in
your case, there's no loss, so it's a bug, but I don't have time to
track down why you're getting it.
