Create a grouped barplot in R using ggplot

Question

I'm trying to create a grouped barplot using ggplot due to the more aesthetically pleasing quality it produces. I have a dataframe, together, containing the values and the name of each value but I can't manage to create the plot it? the dataframe is as follows

          USperReasons      USperReasonsNY                 USuniquNegR
1    0.198343304187759   0.191304347826087                 Late Flight
2     0.35987114588127   0.321739130434783      Customer Service Issue
3   0.0667280257708237    0.11304347826087                Lost Luggage

9   0.0225494707777266  0.0347826086956522                   longlines
10  0.0538426138978371  0.0782608695652174 Flight Attendant Complaints

I tried different methods with errors in all, one such example is below

ggplot(together,aes(USuniquNegR, USperReasons,USperReasonsNY))+ geom_bar(position = "dodge")

Thanks, Alan.

It is unclear what your expected result is, and there is no signs of you attempting to solve this yourself. — mtoto, Apr 02 '16 at 14:46
there are several examples of grouped barplots with ggplot2 on SO — MLavoie, Apr 02 '16 at 14:48

Are you sure your data are numeric? What errors are you getting? — Heroka, Apr 02 '16 at 15:29

df <- reshape2::melt(together, 3)

ggplot(reshape2::melt(df, 3), 
    aes(USuniquNegR, value, fill = variable)) + 
        geom_bar(stat = 'identity', position = 'dodge') + 
        coord_flip() + 
        theme(legend.position = 'top')
