So I am using the "rvest" package to get data from websites. I think the main problem is that this website doesn't provide a nice clear table format that you can directly use it. You have to clean it up to get the desired output.
rm(list=ls())
library(tidyverse)
library(rvest)
##### get data from web #####
url = "http://www.espn.com/nfl/team/schedule/_/name/mia"
tb <- url %>%
read_html() %>%
html_table() # this function is actually going to read all tables at this url
rawdata = tb[[1]] # tb is a list and here we only want the fist table
#### clean up the data #####
names(rawdata) = rawdata[2,] # using the second row as data names
tmp = data[grepl("from",data$TICKETS),] # select rows that contain "from"
tmp2 = tmp[,!duplicated(names(tmp))] # delete columns that have duplicated column names
res = as_tibble(tmp2) # convert to tibble
For the cleaning section, I did it step by step by observing the data. Of course, there are plenty of ways of performing the same task.
