Dear guys, I'm almost there... how can I fix the final problems?
Cheers, Marius PS: the "info" function is the one I will then try to call within splom... library(lattice) library(gridExtra) ## trial 1 info <- function(a,b){ grid.table(as.expression(substitute(expression(alpha==alph, beta==bet), list(alph=a, bet=b))), parse=TRUE, # parse labels as expressions theme=theme.list( gpar.corefill=gpar(fill=NA, col=NA), # make bg transparent core.just="left") # justification of labels ) } xyplot(1~1, panel=function(...) info(0.1, 0.5) ) ## trial 2 info <- function(a,b){ grid.table(substitute(expression(alpha==alph, beta==bet), list(alph=a, bet=b)), parse=TRUE, # parse labels as expressions theme=theme.list( gpar.corefill=gpar(fill=NA, col=NA), # make bg transparent core.just="left") # justification of labels ) } xyplot(1~1, panel=function(...) info(0.1, 0.5) ) On 2011-04-19, at 21:39 , David Winsemius wrote: > > On Apr 19, 2011, at 3:26 PM, baptiste auguie wrote: > >> I'm hoping to release a new version on CRAN soon; the broken state of >> R-forge and my poor understanding of R CMD CHECK results have often >> made me postpone action indefinitely. > > In this case the errors were all mine.
