R devel - Jan 2005 - Object Memory-limits in base and its help document (PR#7468)

Full_Name: Shigeru Mase
Version: 2.0.1
OS: Linux (Debian)
Submission from: (NULL) (222.149.162.192)


help.search("Mem") shows there is an object "Memory-limits"
in the base package.
But commads "Memory-limits", or "Memory-limits()", causes an
error message:
Error: Object "Memory" not found. In addition, help(Memory-limits)
displays the
document for Arithmetic.

No.  It shows there is a *help* document "Memory-limits":

   Help files with alias or concept or title matching 'Mem' using
regular
   expression matching:

   Memory-limits(base)     Memory Limits in R

Try help("Memory-limits"), and see ?help.

As is should, for that is an arithmetical operation.

well, but it doesn't do that in R 2.0.1 (proper or patched) both
on Debian or Redhat [in a terminal:]

  > help(Memory-limits)
  No documentation for 'Memory - limits' in specified packages and
libraries:
  you could try 'help.search("Memory - limits")'

whereas in ESS, it actually does what Shigero Mase expected,
since ESS has it's own {not entirely correct either!} magic
handling of help().
