A research project was conducted on several different islands resulting in the data below:
• Install R and Rcmdr. Refer to R Commander Installation Notes for details: http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html • Import the data: ◦ In Rcmdr. under “Data” menu “Import data” from “text file” ◦ Set the “Field Separator” to “Commas”. ◦ Navigate to the CSV file and select it. • Click the “Edit data set” button to open the data set in a window.. ◦ Make a note of all outliers (to put in the legend of the figure). ◦ Click on the number of each row with an outlier, then right-click and “Delete current row”. ◦ Click OK to save edited data set. • Under “Graphs” choose “Scatterplot matrix...” ◦ Select all three variables. ◦ Click “Plot by groups”, select Gender, and click OK. ◦ Click “Options” and select the checkbox for Least-squares line and click OK.
Screencasts for making multipanel scientific figures using Inkscape
- Think ahead of time. What is your figure going to look like? Should you crop imagery ahead of time? Do you need to adjust image or exposure? (Note: Some journals don't allow digital manipulation of imagery). Do this in a bitmap editing program (e.g. GIMP or Photoshop).
- Do all your work in a folder. Put your image files in there. Save your SVG file in there. Save early and often.
- Import all your images: Either Link or Embed. Note things can be “above” or “below” others. Click or drag over to select. Hold the “shift” key to select multiple objects.
- Composite your images to make your design: Lock proportions to avoid stretching. Turn “snapping” on or off. Set height and width directly to resize. Use Align and Distribute (switch to "relative to first selected").
- Construct one label: Make a square box, make both stroke and fill the same (black or white). Put a text field in and add a letter. Use sans font. Use align and distribute to center letter.
- Duplicate label to make more: Select both, duplicate object, move. Repeat as necessary.
- Finish each label: Replace each letter as necessary. Use Align and Distribute to center. Select both and group. Use align and distribute to put labels at corners of each panel.
- Create arrows: Use the Line Tool to draw a straight line segment (click, click-click). Then use Fill and Stroke tool to set the line width and add arrow head to start (or end).
- Set the Page Size: Open Document Properties. Resize Page to Drawing. Set background to not be transparent (increase alpha channel to 255).
- Export Finished Figure: Export PAGE. Set width to 1200pixels. Save with name “Lastname-Original.png” The resultant PNG file is your finished figure.
Note: Do not share your finished figure or include in your METHODS manuscript until your methods have been followed!
Work in pairs. Each pair should follow a link, briefly discuss, and be prepared to report on the reliability, validity, and trustworthiness of the site. How do you assess these characteristics?
