I'm trying to download a csv file from the Our World in Data website. There are several charts at the end of the post, and each has a "Data" tab that reveals a download link.
When you click the csv downloads directly. The link to the "relative-share-of-deaths-in-usa.csv" button is "https://ourworldindata.org/e9df3be1-29e0-4366-bc14-554bb4ba8be1", but when I use this in RCurl, it downloads an html file. How can I pull into R from the site?
library (RCurl)
download <- getURL("https://ourworldindata.org/e9df3be1-29e0-4366-bc14-554bb4ba8be1")
data <- read.csv(textConnection(download))

pretty new to R and just trying to get my head round web scrapping.
So I want to download into R a CSV file (easy enough I can do that). The issue that i am having is that every month the CSV file name changes on the website, so the URL then also changes.
So is there a way in R to tell it to download the the CSV file without the exact file url?
here is the website i am practicing it on:
https://www.police.uk/pu/your-area/police-scotland/performance/999-data-performance/
Thanks :)
So tried the basic stuff like below, issue is the url will change when the file is updated.
dat <- read.csv(
"https://www.police.uk/contentassets/069a2c11fcb444bbbeb519f69875577e/2022/sept/999-data-nov-21---sep-22.csv"
, header = T)
view(dat)

I'm trying to export this PDF daily and send it by email. Is there a way to write a script that automatically downloads the PDF version of the file?
DifferencesinQueue <- render_diff(diff_data(df, df_og, always_show_header = TRUE))
write.csv(DifferencesinQueue, 'PATH/Updates.csv')```
I'm trying to save a two csv files that can be accessed through this website:
https://www.cenace.gob.mx/Paginas/SIM/Reportes/CapacidadTransferencia.aspx
I only want to save both csv files as data frames in RStudio. I've tried to do this through rvest, but it seems that the data is in the website's back end and this approach is not working.
I try to download a csv file programmatically on a webpage.
Here is the URL.
I tried to use download.file() in R, but there is no link for the csv file.
Can I use R to click the 'CSV' button on top of the webpage to trigger the download process?
You could also directly read the table on the page instead of trying to download the csv:
library(rvest)
url<-"https://e-service.cwb.gov.tw/HistoryDataQuery/MonthDataController.do?command=viewMain&station=466920&stname=%25E8%2587%25BA%25E5%258C%2597&datepicker=2017-02"
session <- html_session(url)
data <- html_table(session)
head(data[[2]])
I was trying to import a hotel reviews dataset into R from website. How do we do this one line of code, without manually downloading it and then importing it using read.csv type functions?
https://data.world/datafiniti/hotel-reviews/workspace/file?filename=Datafiniti_Hotel_Reviews.csv
Clicking on the above link doesn't directly prompt you to download. I tried using the URL function within read.csv().
Thanks for your help.

you need to go to the "share url" in Data World to get the proper link
url2<-"https://query.data.world/s/hvrhbuqej6z2wdlmga4vtpsxx32ig4"
download.file(url2, destfile = "./Data.csv",cacheOK=TRUE)
Data<-read.csv("./Data.csv",header=T,stringsAsFactors = FALSE)
Similar to the answer above, but you can also f you click on the Download button in data.world and click on Share URL, you can copy a one-liner for R to load that table directly from the signed URL:
