Creating a scatter plot for multiple rows in R <p>I have a data frame that looks something like this:</p> <pre><code> Samp1 Samp2 Samp3 Samp4 Samp5 Gene1 84.1 45.2 34.3 54.6 76.2 Gene2 94.2 12.4 68.0 75.3 24.8 Gene3 29.5 10.5 43.2 39.5 45.5 ... </code></pre> <p>I am trying to create a scatter plot where the x-axis are the samples(Samp1-5), and the y-axis are the rows(Gene1-3 and so on), but I want the data of each row to be plotted as a different color on the same plot.</p> <p>Any thoughts on how to do this in R? I am more than willing to use ggplot2, lattice, car or any other package in R.</p>
