calling functions without copying into script window
<p>The default library for my R installation is 
<code>C:\Users\mmstat\Documents\R\win-library\3.3\</code></p>

<p>I also have functions with .txt extensions saved in a second folder 
<code>c:\S library\</code></p>

<p>My problem is that I don't know how to tell R about my function library 'S library' so I don't have to copy and paste the code for the wanted function in my script window and then executing it.</p>

<p>How can I do this?</p>
