[R] Errors while compiling packages with namespace?

[Philippe Grosjean]

Hello,

I try to set up namespaces for packages. It is fine for several of them,
except one whose compilation fails (under Windows XP & R 2.0.0):

---------- Making package svViews ------------
  adding build stamp to DESCRIPTION
  installing NAMESPACE file and metadata
Error in parse(file, n, text, prompt) : syntax error on line 21
Execution halted
make[2]: *** [nmspace] Error 1
make[1]: *** [all] Error 2
make: *** [pkg-svViews] Error 2
*** Installation of svViews failed ***

This kind of error tells me that there is something wrong in my code, making
it impossible to parse, isn't it? However, when I source the code in R,
everything is fine. Also, this package compiled without errors before I
introduced NAMESPACE. The only changes I did in the code (beside adding
NAMESPACE), is to eliminate all "require(....)" and to replace them by
"import" and "importFrom" statements in NAMESPACE. So, I suppose this should
be due to a wrong or missing "import", or "importFrom" directive. Does
anybody has another suggestion?

My question is: how do I know where is the error in my code, given this
message: "syntax error in line 21" while installing NAMESPACE. Obviously, it
is not in "line 21" of any of my original code files in ./R (because I can
source them all without error). At this point, I am completelly lost. Any
help would be welcome. This package contains several hundreds of lines of
code, and NAMESPACE is quite complex:

importFrom(svMisc, listCustoms, getTemp)
importFrom(R2HTML, HTML, HTMLhr, HTMLInsertGraph, HTMLli, HTML.cormat)
importFrom(utils, browseURL, methods)
importFrom(lattice, lset)
importFrom(MASS, lda)

import(svIO, graphics, grDevices, stats)

export(guiViewsCmd,
       guiViewsCSS,
       guiViewsCSSChange,
       guiViewsDir,
       guiViewsDisplay,
       guiViewsFile,
       report,
       reportGraph,
       viewHTMLinit)

S3method(view, default)
S3method(view, data.frame)
S3method(view, function)
S3method(view, matrix)
S3method(view, princomp)
S3method(view, trellis)
S3method(view, ts)

Thank you.
Best,

Philippe Grosjean
