[R] Question regarding mosaicplot

[Jean Vidal]

I tried this : 
> mosaicplot(stoc ~ q9r + segca,data=tmp2,color=T) : works fine.

And now, this :
> mosaicplot(stoc ~ q9r + segca, data=tmp2, color=T, main="Big title")
Error in model.frame(formula, rownames, variables, varnames, extras, extranames,  : 
        invalid variable type

I'm probably stupid and missed something simple in the manual (and wouldn't like to be flamed if insinuating that, may be... a bug ? Oh no !).

It can be done with :
> mosaicplot(table(tmp2$stoc,tmp2$q9r,tmp2$segca),color=T,main="Big title") : works fine.

So, no real trouble for me...
