I'm trying to read in a table into R for this link: http://www.insidestocks.com/optqte.asp?sym=ESU4&view=add&mode=d
My R code is below. For some reason it is not recognizing the table. Perhaps there is a better package for me to use to do this? Any help would be appreciated!
library(XML)
theurl <- "http://www.insidestocks.com/optqte.asp?sym=ESU4&view=add&mode=d"
tables <- readHTMLTable(theurl)
n.rows <- unlist(lapply(tables, function(t) dim(t)[1]))
tables[[whictablesh.max(n.rows)]]
The relevant one is the seventh table.
tables[[7]]
And we get
Strike Open High Low Close Change Volume Open Int Prem ($)
