[Rd] Error in formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3)

[Spencer Graves]

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.
