Hi, Bill et al.:

It happens in the fda package because some of the headers are longer
than typical (e.g., "Repository/R-Forge/DateTimeStamp") and formatDL
dies if the indent argument is too large compared to the width argument.
It might be nice to change formatDL so it never gave such an error, but
did something reasonable when the 'indent' argument was too big.
Changing
if (indent > width/2) stop("incorrect values of 'indent' and 'width'")
to
indent <- min(indent, width/2)
seems reasonable to me.
Thanks. That sounds like a useful patch to me.
Per "www.r-project.org/bugs.html", I will forward this thread
with your suggested patch to the maintainer for formatDL{base} = "R Core
Team <r-c...@r-project.org>".

p.s. Per your earlier email, I changed the code in PackageSum2{sos} to
include the following before the first call to help{utils}:
w0 <-options(width=80)
on.exit(options(w0))
This eliminated the specific error I reported but may not work
with other packages with even longer headers.

This error can arise when getOption("width") is too small. 80 seems to be the
limit for me with R-3.3.2 on Windows.

Hello:
I tried "debug(help)" with the problem mentioned below. It stopped
with a call to "library", from which I generate the following simple
replication of this error:
library(help = 'fda', character.only = TRUE)
Error in formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3) :
incorrect values of 'indent' and 'width'
This was using R 3.3.3 inside RStudio on a Mac, as noted below. This
same "library(help='fda', character.only=TRUE)" ran fine using R Console
3.2.1 under Windows 7.
I also tried debug(library). It died in line 298:
for (i in which(file.exists(docFiles))) pkgInfo[[i]] <-
readDocFile(docFiles[i])
with i = 1 and docFiles[i] =
"/Library/Frameworks/R.framework/Versions/3.3/Resources/library/fda/Meta/package.rds".
This looks like a bug to me. I don't know if it's new since R 3.2.1
or it works fine under Windows 7 but not a Mac.
Thanks,
Spencer Graves
*** NOTES:
1. When I tried "Q" to exit debug mode, I got, "Error retrieving
help: R code execution error." This suggests a bug in "debug", which could
be replicated by trying debug(help) with "help(package='fda',
help_type='text')". It does not want to exit from "help" using "Q". "c"
also fails.
2. For sessionInfo(), see below.

I have this wrapped inside "try" in PackageSum2{sos}, so it doesn't
die, but it also doesn't give me the additional information I want from
help(..., help_type='text')
Is this a bug?
Thanks,
