<p>Recently I’ve been working with a client to help their analysts improve their proficiency with R. A major challenge in engagements like this is figuring out the needs of the analysts, as well as their general attitude to the training.</p>
<p>To address this I created a “Pre Training Survey” to use with my client. The results from the survey helped me shape the final curriculum. Below I share the actual survey I created in case it helps someone else:</p>
<hr>
<ol>
<li>Does R ever frustrate you?</li>
<li>Does R ever intimidate you (e.g. you think “I’ll just never get it”)?</li>
<li>About how many hours a week do you use spend using R?</li>
<li>What sort of things do you currently use R for (it’s OK to say “nothing”)?</li>
<li>What sort of things would you like to use R for (it’s OK to say “nothing”)?</li>
<li>It is important to me that the training is beneficial to <strong>you</strong>. What is one result you would like to get from this training?</li>
<li>During the training I may get a chance to “Pair Program” with some members of your team. Pair Programming simply means working together on a problem at the same computer. During this time you would get to ask me any questions that you like. Are you interested in pair programming during the training?</li>
</ol>
<p><em>Below are a series of technical questions. They are not designed to trick you. Rather, the answers will help me know where to focus my efforts during the training. </em></p>
<p><em>It is perfectly fine to leave these questions blank, or to simply say “I don’t know.” Please do not use google or R to answer any of these questions.</em></p>
<p>Explain the difference between these two lines of code:</p>
<pre>
install.packages(&quot;ggplot2&quot;)
library(ggplot2)
</pre>
<p>Explain the difference between these two lines of code</p>
<pre>
x = 1
x = &quot;1&quot;
</pre>
<p>What do these commands do?</p>
<pre>
?print
print(1:3)
</pre>
<p>Consider this R code:</p>
<pre>
x = c(1,2,3)
</pre>
<p>What is the output of each of these commands?</p>
<pre>
x
x[1]
x[]
</pre>
<p>Consider this R code:</p>
<pre>
x = c(1,2,3)
</pre>
<p>What is the output of each of these commands?</p>
<pre>
x > 1
x[x>1]
</pre>
<p>Consider this program:</p>
<pre>
x = c(1, 2, 3)
x = x * 2
</pre>
<p>What is the final value of x?</p>
<p>What is the output of this program?</p>
<pre>
x = c(1, 2, 3)
for (i in x)
{
    if(x[i] > 1)
    {
        print(x[i])
    }
}

</pre>
<p>Consider this data frame:</p>
<pre>
a = 1:3
b = 1:3
df = data.frame(a, b)
</pre>
<p>What is the output of these three commands?</p>
<pre>
df[1,1]
df[1,]
df$a
</pre>
<p>What does this program output to the console?</p>
<pre>
square = function(x)
{
    x^2
}

square(10)
</pre>
