Simple question, which I surprisingly couldn't find any answer to on SO: how can you give consent for cookies on websites.
I run code like:
require(rvest)
finances <- "https://finance.yahoo.com/quote/MSFT/financials?p=MSFT&_guc_consent_skip=1608408673"
finances <- read_html(finances)
finances <- html_table(finances,header = TRUE)
This give a empty data.frame, and I suspect it is because the websites asks for consent for tracking cookies. How does one give consent to such cookies using rvest?

Similar to this question that I've answered, I'll give you the code to get the data from the table:
library(rvest)
library(V8)
pg <- read_html("https://finance.yahoo.com/quote/MSFT/financials?p=MSFT&_guc_consent_skip=1608408673")
js <- pg %>% html_node(xpath = "//script[contains(., 'root.App.main')]") %>% html_text()
ct <- new_context()
ct$eval(js)
data <- ct$get("App")
incomeStatementHistory <- data$main$context$dispatcher$stores$QuoteSummaryStore$incomeStatementHistory
incomeStatementHistoryQuarterly <- data$main$context$dispatcher$stores$QuoteSummaryStore$incomeStatementHistoryQuarterly
