ggplot2: working histogram plot with labels

Working R code with labels (pdf file of the graphic):

ggplot(sorted,aes(x=colorname,y=count))+
geom_bar(colour=colour_hex_strings_all,  
stat=“identity”,fill=colour_hex_strings_all,width=1,position=
position_dodge(width = 0.005))+scale_x_discrete(limits=
sorted$colorname)+
theme(axis.text.x  = element_text(angle=90, hjust=1,
vjust=0.5,size=1))
