The number of occurences of elements in a vector [JULIA]
<p>I have a vector of 2500 values composed of repeated values and <code>NaN</code> values. I want to remove all the <code>NaN</code> values and compute the number of occurrences of each other value.</p>

<pre><code>y
2500-element Array{Int64,1}:
8
43
NaN
46
NaN
8
8
3
46
NaN
</code></pre>

<p>For example:
 the number of occurences of 8 is 3
the number of occurences of 46 is 2
the number of occurences of 43 is 1.</p>
