Hello All, i was trying to simply run the readHTMLTable on the example published in the package. And on a page I was working on. So running: u = "http://en.wikipedia.org/wiki/List_of_countries_by_population" tables = readHTMLTable(u) returns the following error: Error in tb[["thead"]] : subscript out of bounds looking up this er...

Hi, I can't get the colClasses option to work in the readHTMLTable function of the XML package.

...experiencing. In the searches I've done, it sounds like the existence of the leak is fairly well known. What isn't as clear is exactly how to solve it. The general process I'm using is this: require(XML) myFunction <- function(URL) { html <- readLines(URL) tables <- readHTMLTable(html, stringsAsFactors = FALSE) myData <- data.frame(Value = tables[[1]][, 2], row.names = make.unique(tables[[1]][, 1]), stringsAsFactors = FALSE) rm(list = c("html", "tables")) # here, and free(tables)...

...te and time. Older records, as e.g. "2017-07-09 17:02 (UTC)" appear as e.g. "1499619726149961972621 hours, 59 minutes ago". I don't know how to convert these data to the time formats used in R (POSIXct). The script is very simple and worked before: library(XML) x <- readHTMLTable('url') where the 'url' is the link to the website with the specification of the vessel. I appreciate any help.

...and the best-case scenario when you let your email program send HTML is that what you saw is not what we see (worst case is your email is scrambled on our end). Have you read the documentation for the function you are using? In particular, what about the colClasses argument? If you don't let readHTMLTable guess what the format is (have it read in as character data) then you have a fighting chance to get it right yourself, e.g. as.POSIXct( "2017-07-10 14:04 (UTC)", format="%Y-%m-%d %H:%M (UTC)", tz="UTC" ) ----- [1] http://stackoverflow.com/questions/5963269/how-to-ma...

...gly little credit, just the brickbats for things for which we are not responsible. (We even work hard to port XML to Windows for you, again with almost zero credit.) That URL is a page in UTF-8, as its header says. We have provided many ways to work with UTF-8 on Windows, but it seems readHTMLTable() is not making use of them. You need to run iconv() on the strings in your object (which as it has factors, are the levels). When you do so, you will discover that page contains characters not in your native charset (I presume, not having your locale). What you can do, in Rgui o...
