I am having trouble plotting sorted values inside each facet using ggplot2.

Here is the sample plotenter image description here

ggplot(data=df) + 
    geom_point(aes(y=log(count_neg,10), x= ref_name, colour=replicate)) +             
    facet_grid(condition ~ sub_groups)

What I would like to do is sort the points in each facet by Y values. I tried the following but it didn’t work:

ggplot(data=df) + 
    geom_point(aes(sort(y=log(count_neg,10),decreading=TRUE), 
                   x= ref_name, colour=replicate)) + 
    facet_grid(condition ~ sub_groups)

Raw data here:

df<-structure(list(condition = structure(c(1L, 1L, 1L, 1L, 1L, 1L,

    Try this:

    df$ref_name <- reorder(df$ref_name,-log(df$count_neg,10))    

ggplot(data=df) + 
    geom_point(aes(y=log(count_neg,10), x= ref_name, colour=replicate)) +             
    facet_grid(condition ~ sub_groups)

    or omit the minus sign if you want the opposite ordering. This orders the x axis by the (global) y value. If you intended to order each facet separately, that is somewhat more complicated, in part because it makes the graph considerably more confusing.
