Error when using xray::distributions() with only categorical variables

[bgrich]

When using xray::distributions() with only categorical variables, I received the error:

Error in names(object) <- nm : attempt to set an attribute on NULL

This appeared with both strings and factors.

df_1 <- data.frame(string_dat = c("a", "b", "b"))
xray::distributions(df_1)

df_2 <- data.frame(fact_dat = factor(c("a", "b", "b"), levels = c("a", "b")))
xray::distributions(df_2)

The inclusion of at least one numerical variable appears to fix this problem.

df_3 <- data.frame(numerical_dat = c(1, 2, 2), string_dat = c("a", "b", "b"))
xray::distributions(df_3)

Fortunately, this error doesn't appear to cause any problems with the output from the function.

Thanks for reporting it, it was a silly mistake
