[ad_1] Here you go. library(dplyr) Mean_of_a_group <- dataset %>% group_by(age_group) %>% summarize(happy = mean(happy)) I suggest using ggplot2 to do what you want here. ggplot(data = Mean_of_a_group, aes(age_group, happy))+ geom_point Dummy example library(ggplot2) ggplot(aes(x = disp, y= mpg), data = mtcars)+ geom_smooth(aes(colour = “red”), data = mtcars, stat = “smooth”, formula = y ~ x … Read more

[ad_1] For doing that, you have to remember in which order you are running (reverse or not). So you will have a variable indicating if the order is reverse or not, and change it when you reach the extremities of your counter (0 and 3) And you can optimize the code with using 1 and … Read more
[ad_1] There is a standard function called std::find in the header <algorithm>: #include <iostream> #include <algorithm> int main() { int myarray[6]{10, 4, 14, 84, 1, 3}; if (std::find(std::begin(myarray), std::end(myarray), 1) != std::end(myarray)) std::cout << “It exists”; else std::cout << “It does not exist”; return 0; } Ideone [ad_2] solved Find if an element exists in … Read more
[ad_1] I presume you mean ansi SQl. In general, the answer would be specific to the way the two queries were written. You can write a bad query in either language to produce the same result. However, most of the time, the database vendors code written specifically for that engine will outperform generic SQl for … Read more
[ad_1] I don’t think there is a good way to do this, as your first activity could get collected by the system, and you generally don’t want to do work after onPause has been called. I would move that logic that updates the views into a service that runs in the background. Since it sounds … Read more
[ad_1] I finally got this working by doing the steps outlined above. I have no idea why the decorator method doesn’t work but directly passing clientID did the trick. [ad_2] solved Store Universal Google Analytics inside server session
[ad_1] If your goal is just to remove a row as soon as its checkbox gets clicked, then the following snippet accomplishes that. Note that your checkboxes didn’t have the deleter class; I added that. $(‘.deleter’).click(function () { $(this).closest(‘tr’).remove(); }); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div class=”table1″> <form> <table> <tr> <th>Primary</th> <th>Address</th> <th>Construction</th> <th>Town Grade</th> <th>Select All <br … Read more

[ad_2] solved Curl php not … Read more
[ad_1] I ended up subquerying with this in the SELECT — cast(substring(column FROM ‘[0-9]+’) as int) and this in the WHERE column ~ ‘^\d+$’ in the FROM as its own table. Pulling just the integers i needed from that with IN (1,2,3) [ad_2] solved Pull specific numbers from a column that has numbers and words
[ad_1] Go to https://SLACK.slack.com/threads/team/ (replace SLACK with your slack group name) Enter this in the console, it will scroll through the sidebar and insert the members from the sidebar into an array called storage var storage = []; var el = document.querySelector(‘#team_list_scroller’); el.scrollTop = 0; var last_scroll; var loop = () => { last_scroll = … Read more
[ad_1] You’ve forgot to state the correct question. As I can see from the Java code provided (reverse engineering), all you want is to have MD5 hash code (as a String) for a given file; if it’s your case, you want just to Create MD5 crypto Open the file Compute hash on file stream Represent … Read more

[ad_1] You might want to elaborate and maybe read a little, although something like this shows how you can get data out of the JSON response. <!DOCTYPE html> <html lang=”en”> <head> <meta charset=”utf-8″ /> <title></title> <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js”> </script> <script type=”text/javascript”> $(function() { $.getJSON( “http://yourserver/test.json”, function( data ) { alert (data[“data”][0][“text”]); }); }); </script> </head> <body> … Read more
[ad_1] Alright let’s see. First you call Circle9() that starts the constructor: /** No-arg constructor */ public Circle9() { this(1.0); System.out.print(“C”); } As you can see the constructor first calls this(1.0) This means that another constructor is opened and afterwards we print “C” Alright the next Constructor is: public Circle9(double radius) { this(radius, “white”, false); … Read more
