Y axis doesn't show label name in R

Question

I just started with R , I use RStudio.

Right now I am playing around with plots just to see how they work.

Here is my data:

https://www.dropbox.com/s/wp4gs8qamdo1irk/State_Zhvi_Summary_AllHomes.csv?dl=0

I have been trying to draw a barplot for $Zhvi against $RegionName

Here is my code :

labels <- allHomet$RegionName
mp<-barplot(round((allHomet$Zhvi)/1000,digits=2)[order(labels)],horiz=TRUE,las=1,col=c(palette(heat.colors(6,alpha=1))),
        border=NA,
        main="Price of housing in United states",
        xlab="Price",
        las=2 )!

here is the plot I get

I don't get region name on the y axis,it shows blank .

Can any one tell me how I can make the region name appear?

This is a problem that ggplot2 is ideally suited to dealing with. Its flexibility and modularity make it easy to knock-up graphs like this in no time:

library(ggplot2) # load graphics package
head(df)
fl <- as.character(rep(1:6, length.out = nrow(df))) # fill variable - anything here
ggplot(df) + 
  geom_bar(aes(x = RegionName, y = Zhvi, fill = fl), stat = "identity", position = "dodge") + 
  scale_fill_brewer(type = "qual", name = "") +  # customise colours and legend title
  coord_flip() # make bars horizontal
