R devel - Mar 2017 - Error in formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3)

Hello:


       A call to help(..., help_type='text') fails with
"package='fda":


 > install.packages('fda')
 > help(package='fda', help_type='text')
Error in formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3) :
   incorrect values of 'indent' and 'width'


       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,
       Spencer Graves

Using RStudio 1.0.136 with


 > sessionInfo()
R version 3.3.3 (2017-03-06)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: macOS Sierra 10.12.3

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets
[6] methods   base

loaded via a namespace (and not attached):
[1] tools_3.3.3

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.

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.
