[ad_1] The following should work, I have stored your example input as a dataframe called ‘dat’: library(ggplot2) library(cowplot) plt = ggplot(dat, aes(Income_group, percentage)) + geom_bar(stat=”identity”) + facet_grid(Airport ~.) + background_grid(major=”y”, minor = “none”) + panel_border() plt + theme(axis.text.x = element_text(angle = 90, hjust = 1)) 2 [ad_2] solved In ggplot, how can I plot multiple … Read more
[ad_1] According to this answer, the minimum (emphasis mine) ranges of an integer is -32,767 to 32,767. The actual limits are implementation defined, and are most likely from -2 billion to positive 2 billion. To check the integer limits on your device, you could use the header <limits> as follows: int imin = std::numeric_limits<int>::min(); // … Read more
[ad_1] This may help you below code contains for both to get and post data: public static string PostContent(this Uri url, string body, string contentType = null) { var request = WebRequest.Create(url); request.Method = “POST”; if (!string.IsNullOrEmpty(contentType)) request.ContentType = contentType; using (var requestStream = request.GetRequestStream()) { if (!string.IsNullOrEmpty(body)) using (var writer = new StreamWriter(requestStream)) { … Read more

[ad_1] To access the array, you need to use array index. Instead of using @messages_test = options[‘Messages’][‘IBMessageID’].to_s you need to use, to access to first element the arrayoptions[‘Messages’] array, below code @messages_test = options[‘Messages’][0][‘IBMessageID’].to_s You can iterate the array, if you wish, by using options[‘Messages’] each do |item| puts item[“IBMessageID”] # for illustration end 1 … Read more
[ad_1] For those with a maths background it is a surprising feature that System.out.println(“=” + (-3 % 4)); for example, returns -3 instead of 1 (which would be in the range [0,3]); Edit: in other words, the error message error message: Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: -8 is ultimately caused by (n % m) can … Read more

[ad_1] You have jank, because you have one massive layer being repainted each frame. It is almost 12000 pixels long. You need to find a way to minimize this. To figure this out, turn on “Paint” profiling and turn off the rest. Then just run a quick 2-3 second profile. It will take a bit … Read more
[ad_1] You need to convert your std::string to a std::uint16_t. I’d recommend a stringstream std::istringstream ss(string); // maybe pick a different name std::uint16_t port{}; ss >> port; address.sin_port = htons(port); Be sure to #include <sstream> 2 [ad_2] solved Passing std::string as parameter gives error – htons function
[ad_1] UPDATE FOR THE NEW CLEARER QUESTION: It sees now that I should have added more text to my question.

[ad_1] Your item =…. line, as it stands, just associates a new object with the name item in the function’s namespace. There is no reason why this operation would change the content of the list object from which the previous value of item was extracted.

[ad_1] mysqli_num_rows() can only be used with SELECT queries, it returns the number of rows in the result set. To test how many rows were affected by a modification query, use mysqli_affected_rows(). And the argument to this should be $connect, not $result (which is just a boolean). $result = mysqli_query($connect, $query); if (!$result) { die … Read more
