R - Descriptive analytics summarize multiple column with dplyr : <p>I'm trying to join the mean, median, sd and var of a dataset but I'm failing to do so with dplyr.</p>

<p>Here is a SS with the <a href="https://i.stack.imgur.com/vVd3X.png" rel="nofollow noreferrer">Data</a></p>

<p>I'm just failing to obtain a table containing mean, median, sd and var for each header (Congruent and Incongruent)</p>

<p>The header of the table would still be Congruent and Incongruent and the rows would be each function described above.</p>

<p>This is probably a dupe but I have read a lot of similar questions and I just couldn't achieve what I'm trying, sorry for my rookieness. </p>

<p>Many thanks</p>
