[R] Problem with stripplot

[David Scott]

I have had a problem with stripplot. Documentation does say that method
="stack" is only appropriate for granular data, but I don't think that
means it should fall over.

> difference
 [1]  2.0  1.3  2.8 -2.6 -0.4 -0.4 -1.2 -1.4 -1.0  1.2 -2.6 -1.9
> stripplot(difference)
> stripplot(difference,method="jitter")
> stripplot(difference,method="stack")
Warning in y + (unlist(xo) - 1) * offset * csize : longer object length
        is not a multiple of shorter object length
Error: x and y lengths differ

Here is the code to check it.

difference<-c(2, 1.3, 2.8, -2.6, -0.4, -0.4, -1.2, -1.4, -1, 1.2, -2.6, -1.9)
stripplot(difference)
stripplot(difference,method="jitter")   
stripplot(difference,method="stack") 

I have had the same result on 0.63.2 for windows and 0.63.3 for Sun.
