Plotting a bar chart using lsmeans

I'm trying to plot a bar chart with standard error bars using lsmeans, but I keep getting the same error message:

Error in FUN(X[[i]], ...) : object 'lsmean' not found

I've tried all sorts of different codes to achieve this and never manage to do it.

My model is:

model<-lmer(data=data, Y~X1+X2+X3+X4+(1|Individual))

My lsmeans code (I have back transformed the data after a log transformation on Y:

lsmeans(model,
        ~ X1,
        adjust="tukey")  

X1.post <- lsmeans(model, pairwise ~ X1, type = "response")
X1.post

The code I have just tried is:

ggplot(data) +
  geom_bar( aes(x=X1, y=lmean), stat="identity", fill="skyblue", alpha=0.5) +
  geom_crossbar( aes(x=X1, y=lsmean, ymin=lsmean-se, ymax=lsmean+se), width=0.4, colour="orange", alpha=0.9, size=1.3)

I want to report the lsmeans for X1 which has 5 levels. Please could anyone advise on which code I can use for this purpose?
