Pulling and Pushing

This is a follow up to Pushing Changes.

STOP: Make sure you sent your teacher an email following the last exercise with a link to your Github repository and wait until your teacher has told you they’ve updated your repository before doing this one.

While you were working on your plot of size among lakes, your colleague (who has suddenly developed some pretty impressive computational skills) wrote some code to generate a histogram of scale lengths. To get it you’ll need to pull the most recent changes from Github.

1. On the Git tab click on the Pull button with the blue arrow. You should see some text that looks like:

   From github.com:ethanwhite/gryffindorforever
      1e24ac8..815e600  master     -> origin/master
   Updating 1e24ac8..815e600
   Fast-forward
    testme.txt | 1 +
    1 file changed, 1 insertion(+)
   create mode 100644 youareawesome.txt
   

2. Click OK.

3. You should see the new lines of code in your fish-analysis.R.

   ggplot(fish_data_cat, aes(x = scalelength, fill = length_cat)) +
     geom_histogram()
   

4. Modify this code to look at narrower ranges of scale size classes by setting the bins argument to 80.
5. Save this plot as scale_hist_by_length.jpg using ggsave.
6. Commit the new code and resulting .jpg file by adding both files to the stage and committing with a good commit message, then push this to GitHub.
