Ordered factors not supported in xray::distributions()

[bgrich]

When an ordered factor is included as a variable in xray::distributions() it returns the following warning:

In eval(xpr, envir = envir) : Ignoring variable ord_dat: Unsupported type for visualization.

df_1 <- data.frame(numeric_dat = c(1, 2, 2), 
                   ord_dat = factor(c("a", "b", "b"), levels = c("a", "b"), ordered = TRUE))
xray::distributions(df_1)

This appears to be because the ordered factor has been assigned the class "Unknown" by xray::anomalies() when it is called within xray::distributions(). When checking the class of an ordered factor, it returns a vector of length 2.

class(df_1$ord_dat)
[1] "ordered" "factor"

Since xray::anomalies() only looks at the first element of the class of the variable, it classifies the ordered factor as "Unknown".

xray::anomalies()
 Variable q qNA pNA qZero pZero qBlank pBlank qInf pInf qDistinct    type anomalous_percent

Thanks for the work you've put into this package! I am quite enjoying it and look forward to using it more often.

Sorry, had never heard of the Ordered factor, i'll add it in. I prefer to add new types one by one to avoid plotting wrongly
