Greetings!
Recently when I tried to use lm.influence I get the following error:
Error in .Fortran("lminfl", model$qr$qr, n, n, k, as.integer(do.coef), :
Fortran symbol name "lminfl" not in DLL for package "base"
This occurs on both Linux and Windows platforms (details below).
I presume that the Linux message does not refer to DLLs? :-)
Searching the mail lists and other sources indicates that the fortran code
for lminfluence (lminfl.f) was moved in the source code tree suggesting it
should be found in package stats. Not clear to me why the "hardcoded" path
is package base.
The offending line in the R code for lm.influence is:
res <- .Fortran("lminfl", model$qr$qr, n, n, k, as.integer(do.coef),
There were no other messages from people experiencing errors with
lm.influence on the mailing list.
Can someone else confirm that they are experiencing the same problem?
Also, as a workaround, is there a way of forcing R to look in stats for the
fortran symbol (similar to using the double and triple colon for addressing
specific namespaces)?
<snip> I can run example(lm.influence) and example(influence.measures) without issue on: R version 2.6.1 Patched (2007-11-26 r43541) on an F8 Linux system. I don't see anything immediately obvious in the NEWS file for 2.6.1 patched to suggest that something has changed here. Can you provide a reproducible example here and/or try to upgrade to patched? I would also try to run: R --vanilla from the command line to provide a clean environment to be sure that none of the other packages that you are loading are causing conflicts. HTH, Marc Schwartz
