Time Series Plot reproducing incorrect values in R
<p>I am attempting to plot a simple time series plot of the dataset found here:<a href="https://datamarket.com/data/set/22qf/monthly-champagne-sales-in-1000s-p273-montgomery-fore-ts#!ds=22qf&amp;display=line" rel="nofollow">https://datamarket.com/data/set/22qf/monthly-champagne-sales-in-1000s-p273-montgomery-fore-ts#!ds=22qf&amp;display=line</a></p>

<p>Here is the code the code that I am using:</p>

<pre><code>&gt;setwd("~/Desktop")
&gt;sales&lt;- read.csv("~/Desktop/monthly-champagne-sales-in-1000s.csv", header=FALSE)
&gt;attach(sales)
&gt;msale&lt;-ts(sales, frequency=12, start=c(1950,1))
&gt;plot(msale)
&gt;plot&lt;-ts(V1,V2)
</code></pre>

<p>Both of my attempts to plot the time series below have failed because the sales column shows sale yields in the 200-5000 area. In my attempt to plot the time series above, R is printing out values between 5-80. I figured something was wrong with the sales column dataset so when I printed the following in the console </p>

<pre><code>&gt;View(sales$V2)
</code></pre>

<p>the results yielded this: </p>

<p>Can someone explain what is structure(c  and why it is skewing the data so extensively?</p>
