title: How to create the equivalent to Excel pivot charts in R/ggplot2
body: <p>I do a lot of pivot charts and I'm frustrated by Excel. Three weeks ago (as of 2/20/2015) I started learning R hoping to get more productive. With the bare basics covered, I installed ggplot2 in my R-Studio. I searched for ggplot2 tutorials but couldn't find any relevant to what I need. </p>
  
  <p>Being brand new to Stack Overflow I cannot post a picture to illustrate, but my data often includes 2 continuous variables and 2 discrete variables that I use as factors. I need to calculate and graph the mean ± sd (error bars) of three replicates for Variable.1 on one axis (as bars) plus the mean for three replicates for Variable.2 on the second axis (as scatterplot). </p>
  
  <p>My questions are:</p>
  
  <p>1) is it possible to do this with R/ggplot2?</p>
  
  <p>2) Where can I find instructions/tutorials/etc that show how to do it? </p>
  
  <p>I'm willing to go and search for the needle myself... if I could only find the haystack!</p>
  
  <p>Thanks!</p>
