NAMESPACE and imports

Dear Rxperts,
I am trying to use pdflatex from Hmisc, I get the error message.
"pdflatex
is not available"... The version of R is

version

platform       i386-w64-mingw32
arch           i386
os             mingw32
system         i386, mingw32
status
major          2
minor          15.2
year           2012
month          10
day            26
svn rev        61015
language       R
version.string R version 2.15.2 (2012-10-26)
nickname       Trick or Treat

Is it not available anymore? I created a latex file using "tables"
package
and am unable to create the pdf file ...

Any suggestions welcome!
Thanks,
Santosh

Now I see it.  S3method() wants two arguments so I need to create

multiple

S3method() statements for each generic.

Sort of.  It actually accepts two or three arguments: see package

'tools'

for an example of using three.

Right, I should have said import(Hmisc) instead of

importFrom(Hmisc), but

that does not explain the error message.

Not sure this fixes your problem, but as far as I can know (and

can tell

from the manual:

http://cran.r-project.org/doc/**manuals/r-release/R-exts.pdf<http://cran.r-project.org/doc/manuals/r-release/R-exts.pdf>),

importFrom
needs to know what functions you are importing [e.g.

importFrom(Hmisc,

"latex") importFrom(stats, "anova")].

I am cleaning up the rms package to not export functions not to be
called
directly by users.  rms uses generic functions defined in other
packages.
For example there is a latex method in the Hmisc package, and rms

has a

latex method for objects of class "anova.rms" so there are

anova.rms and

latex.anova.rms functions in rms.  I use:

export(asis,bj,bjplot,bootBCa,**bootcov,bootplot,bplot,**
calibrate,cph,catg,**combineRelatedPredictors,**
confplot,contrast,coxphFit,**cph,cr.setup,datadist,**
effective.df,fastbw,formatNP,**gendata,gIndex,GiniMd,Glm,Gls,**
groupkm,Hazard,hazard.ratio.**plot,histdensity,"%ia%",ie.**
setup,interactions.containing,**legend.nomabbrev,lm.pfit,lrm,**
lrtest,lsp,matinv,matrx,**Newlabels,Newlevels,nomogram,**
num.intercepts,ols,ols.**influence,oos.loglik,pantext,**
Penalty.matrix,Penalty.setup,**pentrace,perimeter,perlcode,**
plot.xmean.ordinaly,pol,pphsm,**predab.resample,Predict,psm,**
rcs,related.predictors,**reVector,robcov,Rq,sascode,**
scored,sensuc,setPb,show.**influence,specs,strat,Surv,"[.**
Surv",survdiffplot,survest,**Survival,survplot,univarLR,**
validate,val.prob,val.probg,**val.surv,vif,which.influence)

importFrom(Hmisc)
S3method(anova, rms)
S3method(latex, anova.rms, bj, cph, Glm, Gls, lrm, naprint.delete,

ols,

pphsm, psm, rms, Rq, summary.rms, validate)

When doing R CMD INSTALL I get: [using R 2.15.3]

** preparing package for lazy loading
Error : c("bad 'S3method' directive: S3method(latex, anova.rms,

bj, cph,

Glm, Gls, lrm, naprint.delete, ", "bad 'S3method' directive:    

ols,

pphsm,
psm, rms, Rq, summary.rms, validate)")
ERROR: lazy loading failed for package ?rms?

Any advice appreciated.
Frank
