The tours in R are Jupyter notebooks. To run them (which we recommend), you need to install IRkernel through https://github.com/IRkernel/IRkernel.
The tours make use of different external libraries such as:
Each time you encounter a new library in a numerical tour, you will need to install it.\ In order to install each of them on the R kernel for Jupyter, you need to run the following line on an R terminal:\
The directory_of_IRkernel_libraries is the place of the subfolder R\library inside the installation folder of Anaconda3 on your computer. Example of the installation of imager:
install.packages("imager","C:\Program Files\Anaconda3\R\library", dep=TRUE)
You can use from the R prompt the command home to locate this directory:
Each tour makes use of a toolbox package that needs to be downloaded as a .zip file, and then unzipped within your working directory (from which you will run the notebooks): (https://github.com/gpeyre/numerical-tours/tree/master/r/nt_toolbox).
Alternatively, you can download the whole numerical_tours: (https://github.com/gpeyre/numerical-tours/tree/master/r/).
The solutions to the exercises are available online.
