Package pafdR provides access to all material from book Processing and Analyzing Financial Data with R. You can find more details here.
With pafdR you can:
pafdR_download.code.and.datapafdR_build.exerciseAll the R code from the book is publicly available in github. Function pafdR_download.code.and.data will download a zip file from the repository and unzip it at specified folder. Have a look in its usage:
if (!require(pafdR)){
install.packages('pafdR')
library(pafdR)
}
my.lan <- 'en' # language of code and data ('en' or 'pt-br')
# dl may take some time (around 60 mb)
pafdR_download.code.and.data(lan = my.lan)
dir.out <- 'pafdR-en-code_data-master'
# list R code
list.files(dir.out, pattern = '*.R')
list.files(paste0(dir.out,'/data'))All exercises from the book are based on package exams. This means that every reader will have a different version of the exercise, with different values and correct answer. I’ve written extensively about the positive aspects of using exams. You can find the full post here
You can create your custom exercise file using function pafdR_build.exercise. Give it a try, just copy and paste the following chunk of code in your R prompt.
if (!require(pafdR)){
install.packages('pafdR')
library(pafdR)
}
my.lan <- 'en' # language of exercises
my.exercise.folder <- 'pafdR-exercises' # name of folder with exercises files (will download from github)
my.pdf.folder <- 'PdfOut' # name of folder to place pdf file and answer sheet
pafdR_build.exercise(lan = my.lan,
exercise.folder = my.exercise.folder,
pdf.folder = my.pdf.folder)
list.files(my.pdf.folder)These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
