Question

I crawl web data in R.

library(rvest)
library(stringr)
getwd()
body = c()
url = c()
url_base = "web address"

for(i in 1:4)
+ {
+     
+     url_crawl = paste(url_base, i , sep="")
+     b_css = "css code"
+     
+     hdoc = read_html(url_crawl)
+     
+     b_node = html_nodes(hdoc, b_css)
+     
+   }

Error in open.connection(x, "rb") : Could not resolve proxy: myproxy.server.com

I used this code but now i can't use it. how to solve this problem?

Answer 1

I solved it. This happens because my computer or program has a proxy server. So initialize. This code will be fine.

Sys.setenv("http_proxy"="")
Sys.setenv("no_proxy"=TRUE)
Sys.setenv("no_proxy"=1)
