loadNamespace and versionChecking and the otherpackage::otherfun syntax
This is an enquiry not so much about what the code for loadNamespace does,
but
rather about the intent and design of loadNamespace, and how it interacts
with
the `::` function, which seems to me to follow a slightly different
philosophy.
It is not an urgent question - the issue that started me wondering has been
resolved another way - but I would like to complet...

Problem understanding behaviour of versionCheck for loadNamespace (and when versions for Imports packages are checked)
Hi Duncan
The difference is that in your call to loadNamespace, the versionCheck list
has 3 components (name, op and version), whereas the documentation only
mentions 2 (op and version).
loadNamespace 'works' for me provided I add a third component to the list
(even a nonsense one).
What I haven't yet had the fortitude to do is track down through...

Problem understanding behaviour of versionCheck for loadNamespace (and when versions for Imports packages are checked)
Hi Duncan,
Many thanks (yet again).
With the hint given by your earlier email (viz that currently loadNamespace
expects a 3rd component called name in the list that is used for the
versionCheck argument) I had another look at what was going on with my toy
examples yesterday evening. I'm still working on my issue, but thus far I
have:
1) Confirmed that internal calls to loadNamespace triggered by

package1 installed in my .libPath().
It was only when I simulated a user who has and older version of the
Imported package1 (by overwriting the later version of package 1 with an
earlier version), then trying to load or attach package2 that the (failure
of the version checking) at loadNamespace time for package1 became apparent
(well apparentish after quite a bit of digging)

Problem understanding behaviour of versionCheck for loadNamespace (and when versions for Imports packages are checked)
...e wrong way (e.g. too verbose or lacking in crucial
detail or in the wrong format) please let me know
I am trying to understand when the version constraints for packages which
appear in the Imports field of a DESCRIPTION file are checked.
Along the way I've hit a snag understanding what loadNamespace with the
versionCheck argument set does. The core of my query is 'am I doing
something wrong, or have I stumbled across a bug?'. Probably the former,
but after several days I still can't figure it out, so any guidance, hints
or outright help would be much appreciated.
Thanks in a...

...et of steps to illustrate a bug, then
reporting on bugs.r-project.org is the way to get it recorded.
Reporting it on this list is really hit and miss. But I think from your
previous description, something else is going on. When I try to load a
namespace with a bad version number, I get an error:
loadNamespace("rgl", versionCheck=list(name="rgl", op=">",
version=package_version('3.0')))
Error in loadNamespace("rgl", versionCheck = list(name = "rgl", op =

I would have assumed they are checked when you try to install the
package. If you ask for version 3.0, and only have 0.3, the install
should fail.
But as you've found, the documents say something else...

Speed-up/Cache loadNamespace()
Dear all,
in our current setting we have our packages stored on a (rather slow)
network drive and need to invoke short R scripts (using RScript) in a
timely manner. Most of the script's runtime is spent with package loading
using library() (or loadNamespace to be precise).
Is there a way to cache the package namespaces as listed in
loadedNamespaces() and load them into memory before the script is executed?
My first simplistic attempt was to serialize the environment output
from loadNamespace() to a file and load it before the script is started.
How...

improve 'package not installed' load errors?
Hi R-devel,
One of the more common issues that new R users see, and become stumped
by, is error messages during package load of the form:
> library(ggplot2)
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()),
versionCheck = vI[[j]]) :
there is no package called 'Rcpp'
Error: package or namespace load failed for 'ggplot2'
Typically, error messages of this form are caused simply by one or
more dependent packages (in this case, 'Rcpp') n...

Better error message in loadNamespace
Hi
I?ve just spend a bit of time debugging an error arising in `loadNamespace`. The bottom line is that the `vI` object is assigned within an `if` block but expected to exist for all of the remaining code. In some cases where the package library has been corrupted or when it resides on a network drive with bad connection this can lead to error messages complaining about `vI...

Erro in loadNamespace
Dear list,
Iget the following error message:
> help.search("omit.na")
Error in loadNamespace(name) : package 'tools' does not have a name
space
I do not quite understand what it means in this case. Is something
corrupt in the installation?
I run R-1.8.1 in Linux RedHat 9 with kernel 2.6.2 on Intel P4.
