Instructions for Getting R

First:

Select your preferred download platform for your operating system (Linux, macOS, Windows) and follow the link.

For Windows

Click base
Click on the Download R 4.4.1 for Windows link (or the latest version)
This downloads a .exe file which you should be able to double click (you need to have write access on your computer)

Click the .exe file (you may have to give permission)
Select the language you want and press OK to start the Setup Wizard

You should be able to accept all the default settings in the setup program (keep pressing Next) OR you might prefer selecting “customized startup” when it asks and then just changing the MDI option to SDI (and accepting all other defaults)
By default, the software will be placed in C:\ProgramFiles\R\R-4.2.1

For MacOS X

Scroll down and click a link for R-4.4.1.pkg if you have Mac OS X 11 (Big Sur) or higher, otherwise you can use another version
Double click on the resulting R icon to install the program.

Instructions for Getting RStudio

In addition you may want to download R Studio. Follow the download button here:

http://rstudio.org/download/ (will send to posit.com/products/open-source/rstudio)

You want the RStudio Desktop version (Open Source Edition). Press the Download RStudio Desktop button. Then select the Installer.

For R Markdown

Within RStudio, in the lower right window select Packages. If knitr is listed there, check it. If not, check Install Packages, type in knitr in the Packages line and press Install. Now you can select it. Now you can select File > New > R Markdown to create an R Markdown document or File > Open to open an existing .Rmd file.

Example: To load data and the workspace:

```{r}

OldFaithful <- read.delim("http://www.rossmanchance.com/iscam2/data/OldFaithful.txt")

View(OldFaithful)

attach(OldFaithful)

load(url("http://www.rossmanchance.com/iscam3/ISCAM.RData"))

```

Instructions for Loading ISCAM Workspace in R

1. Make sure R is downloaded to your computer

2. Go to this webpage: http://www.rossmanchance.com/iscam4/files.html

On many computers, you will be able to click the ISCAM R Workspace link and it will download the .RData file and launch R. On other computers, you may need to select R from a list of programs (if it doesn’t automatically recognize the .RData extension).

If this works, you are encouraged to always follow these steps to launch R.

If this doesn’t work (especially Mac users), then you have the option of saving the .RData file to your computer. If this option isn’t obvious you can right-click on the link (PC) or use alt-click (Mac) to be able to save the file. For R to recognize this file, it must have the .RData extension. If your file does not have this extension, change the file name. Then in R, you can select File > Load Workspace and direct R to this file. (You can also use the pull-down menu to select “all file types” if R is not seeing this file.)

Saving Graphs

You should be able to click on the graph and copy (e.g., ctrl-C on PC which places it on the clipboard, or a snipping tool) and then paste (e.g., ctrl-V) into a word processing file. (See also the options under the Export tab.) It’s easiest if the format of these pictures in Word is “in line with text.”
