Importing data type 1,000 (thousands) of html

I'm importing data from the public database:

link

with the following code:

library(rvest)

for (i in 1:8){
    url_BF <- sprintf('http://bolsafamilia.datasus.gov.br/w3c/consol_uf_cobertura_bfa.asp?gru=5&vigencia=%02d&vigatual=N&uf=%02s&regional=00&regiaosaude=00&cob=1&brsm=1', 2*i+18,"SC")
    html_BF <- url_BF %>%
      httr::GET() %>%
      httr::content('text', encoding = 'latin1') %>%
      xml2::read_html() %>%
      rvest::html_nodes('table')

    data_BF <- html_BF[3] %>%
      html_table(header = TRUE, fill = TRUE)
    data_BF <- as.data.frame(data_BF)

    if(i >= 1 & i < 5){
      linhas = c(294,295)
    }else if(i >= 5){
      linhas = c(296,297)
    }

    data_BF <- data_BF[-linhas,]
    data_BF <- data_BF %>% select(c(1,2,3,4))
    data_BF <- data_BF %>% mutate(ANO = 2009+i)

    if(i == 1){
    data_BF_ano <- data_BF  
    }else if(i > 1){
    data_BF_ano <- data_BF_ano %>% full_join(data_BF)
    }
}

After extracting the table of interest and transforming it into data.frame , R is understanding the numeric values "1,000" as decimals, however the point indicates thousands according to the database.

How do I make it understand that this is a thousand or how can I remove the point without changing the data structure?
