Dear Frank,
I have a Sweave document in which I export anova (aov) tables to Latex and calculate some summary statistics with summarize{Hmisc} for a graph (as in the example below).
I currently use the following code for the aov tables:
<<results=tex>>=
tmp <- datGrassHC[datGrassHC$Loc > 0 & datGrassHC$Loc < 9 ,]
tmpAov <- aov(Height~Geology*Altitude*Origin*BinInOut , data=tmp)
tmpTable <- xtable (tmpAov ,
caption="ANOVA table for vegetation height.",
label="tab:AnovaHeight"
)
print.xtable(tmpTable, type="latex", floating=TRUE,
table.placement="ht", caption.placement="top",
latex.environments=c("center"))
)
@I used xtables, because it has a working aov example. I would be happy to use an alternative if I knew how! Would you have sample code to illustrate how to export an aov table to Latex using latex{Hmisc}.
Thanks very much for your help,
Sander.

The Sweave code below runs fine, as it is. However, an error occurs when the line 'library(xtable)' is uncommented:
Error: chunk 1
Error in "label<-"(`*tmp*`, value = "month") :
no applicable method for "label<-"
Is anybody aware of this and knows a workaround?
Thanks,
Sander.

I feel this is an xtable problem because Hmisc has being using label and label<- since 1991.
