Dear r-devel list members,
By placing a call to the new (with R 2.15.1) globalVariables() in the
development version of the Rcmdr package, I've succeeded in reducing the
"notes" produced by R CMD check from dozens to two. But I still get the
following notes, even though '.commander.done' is in the call to
globalVariables():
------------- snip ------------
* checking R code for possible problems ... NOTE
Commander: no visible binding for '<<-' assignment to '.commander.done'
(C:/Users/John Fox/workspace/Rcmdr/R/commander.R:653)
closeCommander: no visible binding for '<<-' assignment to
'.commander.done' (C:/Users/John
Fox/workspace/Rcmdr/R/file-menu.R:142)
------------- snip ------------
Is there a way to get rid of these notes (without, of course, removing the <<-
assignments)?
Finally, here's a rough function that I used to compose the globalVariables()
command from the package check summary; it's probably not bullet-proof, but
perhaps others will find it useful for packages, like the Rcmdr, that currently
generate many notes about global variables:
------------- snip ------------
findGlobals <- function(filein="00check.log", fileout="globals.R"){
checklog <- readLines(filein)
whichline <- which(grepl("checking R code for possible problems .* NOTE",
checklog))
checklog <- checklog[-(1:whichline)]
whichline <- which(grepl("checking Rd files", checklog))
checklog <- checklog[-(whichline:length(checklog))]
globals <- gsub(".*no visible binding for global variable[ ]*", "", checklog)
globals <- gsub(".*no visible global function definition for[ ]*", "",
globals)
globlas <- gsub(".*no visible binding for '<<-' assignment to[ ]*", "",
globals)
globals <- globals[globals != ""]
globals <- sub("^ *", "", globals)
globals <- sub(" *$", "", globals)
whichentries <- which(grepl(":", globals))
globals <- globals[-whichentries]
globals <- gsub(".* ", "", globals)
globals <- unique(globals)
cmd <- paste("if (getRversion() >= '2.15.1') globalVariables(c(",
paste(globals, collapse=", "), "))", sep="")
cmd <- strwrap(cmd)
writeLines(cmd, fileout)
}
------------- snip ------------
Any help would be appreciated.
John
