get url table into a `data.frame` R-XML-RCurl

由 二次信任 提交于 2019-12-08 08:41:18
问题 I'm trying to get the table of an url into a data.frame . In other examples I found the following code worked: library(XML) library(RCurl) theurl <- "https://es.finance.yahoo.com/q/cp?s=BEL20.BR" tables <- readHTMLTable(theurl) As the warning says the table doesn't seem to be XML Warning message: XML content does not seem to be XML: 'https://es.finance.yahoo.com/q/cp?s=BEL20.BR' Alternatively, getURLContent(theurl, ssl.verifypeer = FALSE, useragent = "R") works but don't know how to extract

Using twitteR through a proxy server

由 痞子三分冷 提交于 2019-12-08 02:09:58
问题 I'm trying to download Twitter data using the twitteR package. I keep getting the error message "Error in function (type, msg, asError = TRUE) : couldn't connect to host" I believe this is because I'm doing this on my work computer and I need to pass the details of the proxy server.
