Reorder barplot in ggplot

[you_y]

Hi i want to reorder barplot according to class.

This ggplot code does not appear in the order of classes when displayed as a plot.

Can you please let me know what I am missing?

@you_y

in the order of classes

Is this what you mean?

    geom_errorbar(aes(xmin = len - sd, xmax = len + sd),
                  width = 0.2,
                  position = position_dodge(.9)) +

If not, what should be the order?

Thank you for your help andresrcs.

I am sorry that i did not explain properly.

I want to make this plot like this. For example,

The y-axis is made by family, but I want to sort by the phylum that corresponds to the family.

[andresrcs]

families %>% 
    arrange(class, len) %>% 
    ggplot(aes(y = fct_inorder(dose), x = len, fill = supp)) +
    geom_col(color = "black",
             position = position_dodge()) +
    geom_errorbar(aes(xmin = len - sd, xmax = len + sd),
                  width = 0.2,
                  position = position_dodge(.9)) +
    labs( y = "Relative abundance (%)")+
    theme_classic() +
    scale_fill_manual(values = c('Black', 'Red'))
