Mac users: To download an R (file names ending with .R) or a data file (file names ending with .dat) using a Mac do the following: Firefox or Safari: (1) Open a web browser window (2) Go to the class web site http://ic.ucsc.edu/~ammoore/ocea90 and select the folder that you want (e.g. R or ASSIGNMENTS) 1 (3) Using your mouse or touch pad, position the cursor over the highlighted link to the desired file name (e.g. brownian_motion.R) and left or right click. This will open the file in the browser window. (4) From the “File” menu tab at the top of your web browser select “Save As…” from the drop down menu that appears. (5) Select the name of the folder where you want to save the file (e.g. R_INTRO or HW1). WARNING: Mac’s have a habit of appending “.txt” to the end of any file with a format that they do not recognize (e.g. the example file brownian_motion.R may be saved as brownian_motion.R.txt). This is likely to happen with the files that have names that end with .R and .dat that you will be using for the class assignments. It is very important that you DO NOT let your Mac append a “.txt” to the end of any file. If this happens the R programs will not be recognized by R and/or the data files that each program reads will not be recognized when you try to run it. Your Mac will usually give you the option of overriding the “.txt” append or you can manually remove the “.txt” part of the name in the “Save As” dialogue box. (6) If you do inadvertently save any file with “.txt” appended to the end of the name you MUST rename immediately it to remove the “.txt” suffix and restore the original name. (7) At this point you should find that the desired file is in the desired directory.
