I am trying to do barplots.
When i add this command to put bars in order

scale_x_discrete(limits=c("Nitrogen","Methane","Carbon","sulfate","Thiosulfate","nitrification","nitrate"))

some bars were empty.
I had this error Warning message:
Removed 18 rows containing missing values (geom_bar).

how can I fix it? Thank you

df_sumzd=group_by(df_long,pathway,Samples) %>% summarise(mean=mean(length),sd=sd(length))

p=ggplot(df_sumzd,aes(x=pathway,y=mean,fill=Samples))+
  geom_bar(stat="identity",position="dodge") +
  geom_errorbar(aes(ymin=mean-sd,ymax=mean+sd),width=0.25,
                size=1,position= position_dodge(0.9),alpha=0.3)+
  theme(axis.text.x = element_text(angle = 45, hjust = 1))+
  scale_x_discrete(limits=c("Nitrogen","Methane","Carbon","sulfate","Thiosulfate","nitrification","nitrate"))
p
