webscrapping data

[Athar]

Hi

I want to retrieve data from this link.

[UFJF - Programas de Ingresso]

By rvest package, please guide me how can I retrieve data from this link into RStudio automatically by coding.

Thanks

Good. What have you tried? The table looks a bit tricky being in a dataTables_wrapper.

This is the top line anyway:

library(tidyverse)
library(rvest)

url <- "http://www4.vestibular.ufjf.br/2021/notaspism1/A.html"

read_html(url) %>%
  html_nodes('table') %>% 
  .[2] %>%
  html_table(fill = TRUE) %>%
  as.data.frame()

not working for the data in table

[williaml]

Yeah I know. It is just the header. It might be useful for you or someone else (or me later).

Also, just post the code, not the screenshot.

[Athar]

can you please help me to retrieve data?

[williaml]

Did you try anything yourself? Post what you tried.

library(XML)
library(rvest)
simple <- read_html("http://www4.vestibular.ufjf.br/2021/notaspism1/H.html")

  
tbls <- html_nodes(simple, "table")
head(tbls)


tbls2_ls <- list()

  tbls2_ls$example <- simple %>%
  html_nodes("#example") %>% 
  html_table(fill = TRUE) %>%
  .[[1]]

str(tbls2_ls)
