r - getURL (from RCurl package) doesn't work in a loop -

i have list of url named urllist , loop on source code each of url :

for (k in 1:length(urllist)){     temp = geturl(urllist[k]) } 

problem random url, code stuck , error message:

error in function (type, msg, aserror = true)  :      transfer closed outstanding read data remaining 

but when try geturl function, not in loop, url had problem, works.

any please ? thank

hard tell sure without more information, requests getting sent quickly, in case pausing between requests :

for (k in 1:length (urllist)) {     temp = geturl (urllist[k])     sys.sleep (0.2)  } 

i'm assuming actual code 'temp' before writing on in every iteration of loop, , whatever fast.

you try building in error handling 1 problem doesn't kill whole thing. here's crude example tries twice on each url before giving up:

for (url in urllist) {     temp = try (geturl (url))     if (class (temp) == "try-error") {         temp = try (geturl (url))         if (class (temp) == "try-error")             temp = paste ("error accessing", url)         }         sys.sleep(0.2)  }
