here are links to some of my web apps. They are (generally) written with R shiny.
To run these apps on your own computer do the following.
1) Download and install R from here
2) Start R by clicking the icon on the desktop. Copy the following text into R and hit enter
install.packages(c("shiny","ggplot2"))
you will be asked to pick a download site from a list, just pick any. It will then install a number of packages. When it is done close R by clicking on the x in the upper right corner. You will be asked whether you want to save something, just say no.
and hit enter. It will give you a list of the available apps, just type the name of the one you want and then enter. When you are done go back to R, hit the Esc key and close the program by clicking on the x in the upper right corner. You will be asked whether you want to save something, just say no
Note to Instructors: these apps are freely available to anyone. I would appreciate, however, if you let me know that you are using them, as well as your experiences with them. Also, if you have any suggestions for improvements, additions or whole new apps, please let me know!
Some suggestions for what to do with the apps can be found here
