rawr

Websites containing R code sometimes necessitate tedious copy/pasting of code blocks from the website to your code editor in order for you to be able to run the code for yourself.

rawr takes care of this.

R Code from Popular R websites

Retrieve R code from a website to your clipboard with rawr_to_clip(), here are some examples:

# install.packages("rawr")
library(rawr)

# CRAN vignettes
rawr_to_clip("https://cran.r-project.org/web/packages/tidytext/vignettes/topic_modeling.html")

# Stack Overflow
rawr_to_clip("https://stackoverflow.com/questions/58248102/date-input-dt-r-shiny")

# Kaggle
rawr_to_clip("https://www.kaggle.com/vrtjso/mercari-eda-more-info-than-you-can-imagine")

# Datacamp
rawr_to_clip("https://www.datacamp.com/community/tutorials/sentiment-analysis-R")

# Github 
rawr_to_clip("https://github.com/hadley/vis-eda/blob/master/travel.R")

# Blogdown sites
rawr_to_clip("https://www.jtimm.net/2019/04/14/lexical-change-procrustes/")

Other functionality

Write output to a temp file

rawr("https://www.kaggle.com/vrtjso/mercari-eda-more-info-than-you-can-imagine", to_file=T)

Write output to a specific file

rawr("https://www.kaggle.com/vrtjso/mercari-eda-more-info-than-you-can-imagine", file_path="mynewfile.R")

Some sites have > 1 way of identifying R coode. If rawr() returns no result (or if the result is non-sense), try another method

"https://www.datacamp.com/community/tutorials/keras-r-deep-learning" %>% rawr %>% cat
# no result

"https://www.datacamp.com/community/tutorials/keras-r-deep-learning" %>% rawr(method = 2) %>% cat 
# returns correct output
