Thanks for the report. This is due to rep(NULL, length.out=...) now giving a warning. As Prof Ripley has mentioned, a similar bug was fixed elsewhere, but this one still persists. I haven't yet found an easy way of fixing all of these, so if you find more instances, please report them to me (or file a bug at https://r-forge.r-project.org/tracker/?func=browse&group_id=638&atid=2567), and I'll take a look as soon as possible. -Deepayan > ## I first detected the problem in > ##### R Under development (unstable) (2012-07-24 r59961) ## windows > ##### R Under development (unstable) (2012-08-02 r60091) ## macintosh > ## The problem still exists in > ## R Under development (unstable) (2012-08-13 r60245) -- "Unsuffered > Consequences" > ## downloaded from lib.stat.cmu.edu Wed Aug 15 2012 11PM EST > > >> tmp <- data.frame(y=rnorm(10), g=rep(ordered(c("A","B")), 5)) >> bwplot(y ~ g, data=tmp, > + key=list( > + text=list(c("A","B"), col=c("blue","red")), > + points=list(pch=c(17, 16), col=c("blue","red")), > + space="top", columns=2, border=TRUE, > + title="Treatment", cex.title=.9 > + ) > + ) > Warning messages: > 1: In FUN(X[[9L]], ...) : 'x' is NULL so the result will be NULL > 2: In FUN(X[[9L]], ...) : 'x' is NULL so the result will be NULL > 3: In FUN(X[[9L]], ...) : 'x' is NULL so the result will be NULL > 4: In FUN(X[[9L]], ...) : 'x' is NULL so the result will be NULL > 5: In FUN(X[[9L]], ...) : 'x' is NULL so the result will be NULL >> version > _ > platform i386-w64-mingw32 > arch i386 > os mingw32 > system i386, mingw32 > status Under development (unstable) > major 2 > minor 16.0 > year 2012 > month 08 > day 13 > svn rev 60245 > language R > version.string R Under development (unstable) (2012-08-13 r60245) > nickname Unsuffered Consequences >> > > [[alternative HTML version deleted]] > > ______________________________________________ > R-devel@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-devel ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
