Tables Package Ampersand Quoting

There seems to be some inappropriate quoting in the tabular function from the tables package. Consider this example:
This turned out to be different than I thought at first. It was simply that I mis-used the latexTranslate function from the Hmisc package. I'll be committing some different changes soon. Duncan Murdoch
library(tables)
sampledf <- data.frame( Manufacturer=c(rep("Joe & Co.",6)
,rep("\\tabular, Inc.",4))
, Tool=rep(c("Shovel","Screwdriver","Harpoon"
,"Items","Stuff"),each=2)
, When=rep(c("List","After"),times=5)
, Price=c(180,190,190,180,200,200,140,145,150,140)
)
sampledf$MfrTool <- with( sampledf
, factor( paste( Manufacturer, "-", Tool ) ) )
tabular( MfrTool ~ When * Price * identity, data=sampledf )
which produces for me:
When
After List
Price Price
MfrTool identity identity
\\textbackslash{}tabular, Inc. - Items 145 140
\\textbackslash{}tabular, Inc. - Stuff 140 150
Joe \\textbackslash{}& Co. - Harpoon 200 200
Joe \\textbackslash{}& Co. - Screwdriver 180 190
Joe \\textbackslash{}& Co. - Shovel 190 180
Although I do intend to pass this through the latex() function, I think
that in this representation the substitution of '\textbackslash{}' for
'\' is premature, and I am not sure why the backslash is getting doubled
here. In any event, the ampersand in 'Joe & Co.' is getting a '\' added
to it (which it shouldn't here), and then when I pass this through the
latex function I get:
latex(tabular( MfrTool ~ When * Price * identity, data=sampledf ))
\begin{tabular}{lcc}
\hline
& \multicolumn{2}{c}{When} \\
& After & \multicolumn{1}{c}{List} \\
& Price & \multicolumn{1}{c}{Price} \\
MfrTool & identity & \multicolumn{1}{c}{identity} \\
\hline
\textbackslash{}tabular, Inc. - Items & $145$ & $140$ \\
\textbackslash{}tabular, Inc. - Stuff & $140$ & $150$ \\
Joe \textbackslash{}& Co. - Harpoon & $200$ & $200$ \\
Joe \textbackslash{}& Co. - Screwdriver & $180$ & $190$ \\
Joe \textbackslash{}& Co. - Shovel & $190$ & $180$ \\
\hline
\end{tabular}
where 'Joe & Co.' has become illegal TeX.
