I'm trying to plot some time series data. My plot looks like the following: 
[![Plot displaying date on y axis?](https://i.stack.imgur.com/CNwUW.png)](https://i.stack.imgur.com/CNwUW.png)

I'm uncertain as to why it displays the date as such. I'm using R Markdown in R studio. Below is my code:

```
agemployment<-read.csv("Employment-Level1.csv", header=TRUE)

```

Tried to change the class of Date:
 `as.Date(as.character(agemployment$Date),format="%m%d%Y")`

That did nothing. Rest of code here:

```
`attach(agemployment)
 View(agemployment)
 head(agemployment)

 agemployment<-ts(agemployment,frequency=12,start=c(2008, 1))

 plot(agemployment, col="black", main="Agriculture Employment Level", 
     ylab="Total Employment Level (Thousands)", ylim=c(0, 250),lwd=2, 
     xaxs="i", yaxs="i", lty=1)'

```

This produces the above plot. I'm uncertain what I'm doing wrong. I would appreciate any help. Thank you!

EDIT:
