There are two ways: 1) Attaching the data: attach(data1) And then this code should work: cor(V1, V2) 2) Using $ for accesing columns in a dataframe cor(data1$V1, data1$V2) solved Object not detected in R [closed]
The query works in MySQL when the statement is as generated by Access iteself. No change required. Here is the answer below: FROM qryvw_employees INNER JOIN (tbl_clients INNER JOIN tbl_assignments ON tbl_clients.`PAN` = tbl_assignments.`PAN` INNER JOIN tbl_tasks ON tbl_assignments.`Assignment_ID` = tbl_tasks.`Assignment_ID` INNER JOIN qryvw_subtasks ON tbl_tasks.`TaskID` = qryvw_subtasks.`TaskID`) ON qryvw_employees.`ID` = tbl_tasks.`Assigned_To` solved How do … Read more
Long story short, the Pi is too complex hardware-wise to operate without an OS (for the vast majority of tasks, anyway). An operating system is essentially an environment for your program to work in. It provides standardized means to use and manage hardware, interrupts, storage (incl. filesystems), I/O etc. What is more inportant, it does … Read more
Instead of registering receiver in manifest , register it in Activity and pass interface to interact on network state change NetworkCallback.java interface NetworkCallback{ void onStateChange(); } ConnectionBroadReceiver.java import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.net.ConnectivityManager; import android.net.NetworkInfo; public class ConnectionBroadReceiver extends BroadcastReceiver { private NetworkCallback callback; public ConnectionBroadReceiver(NetworkCallback callback){ this.callback = callback; } @Override public … Read more
Try this way. but you have to confirm that each row list length must equal to 6. list1 = [] list2 = [] with open(‘example.log’) as f: for i in f.readlines(): if (len(i.split(‘,’)) == 6): list1.append(i.split(‘,’)[4]) list2.append(i.split(‘,’)[5]) print(list1) print(list2) 1 solved Reading log files in python
You have not included your files in your git index before commit git will not keep track of that file changes in the commit. As by default ignored files are not added in git index I guess it is not added to the commit. In that case, using Git, you can’t. But if you are … Read more
We can try using str.replace here: df[“first_middle_name”] = df[“full_name”].replace(“\s+\S+$”, “”) See the above regex replacement working in the demo link below. Demo solved Removing last words in each row in pandas dataframe
The biggest error is while(loop_counter != 21); where the trailing ; will make the loop infinite. 4 solved Where did i make a mistake in my program i think its a logical error but i cant quite find it [closed]
I believe your goal is as follows. You want to copy the cell “B” to “BW” when the cell “BY” is edited to 1. You want to run the script by a trigger. In this case, how about the following modification? Modified script: Please copy and paste the following script to the script editor and … Read more
The recursive function. void recSeq(int counter){ if (counter <= 0 ) return; // first the exit condition int value = counter -1; recSeq(value ); // go down to the bottom, in order to print values from lovest values to higher System.out.print(” “+(int)Math.pow(2, value )); // print the value } on Exit: recSeq(6); // 1 2 … Read more
That’s probably because there are some dependencies that are resolved differently in each case, depending on who is calling this method. In some frameworks, you have something like a state, when request come then the server initializes some variables, for instance a session object for the particular user in which you can store some information. … Read more
You should add an event that will call the code once the document has completed loading. private void Form1_Load(object sender, EventArgs e) { webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted; } void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { button2_Click(sender, e); } 2 solved Execute two buttons with single click
but can that iterator be converted to char array ? Yes Iterator#next() will give you string (because List has generic type String) that can be used to perform any kind of string operation. See the code below put it in main method and run. String[] str = {“Sam”, “Mohit”, “Laksh”, “Nitesh”}; List<String> list = new … Read more
You can use reduce to create such function. function getMin(data) { return data.reduce(function(r, e, i) { let absR = Math.abs(r), absE = Math.abs(e); if (absR > absE || i == 0 || (absR == absE && e > r)) r = e return r }) } console.log(getMin([1.5, -1, 0, 5, 5.5, -4])) console.log(getMin([1.5, -1, 5, … Read more
You can use Generics with where TValue : ICloneable constraint: public static Dictionary<TKey, TValue> deepCopyDic<TKey, TValue>(Dictionary<TKey, TValue> src) where TValue : ICloneable { //Copies a dictionary with all of its elements //RETURN: // = Dictionary copy Dictionary<TKey, TValue> dic = new Dictionary<TKey, TValue>(); foreach (var item in src) { dic.Add(item.Key, (TValue)item.Value.Clone()); } return dic; } … Read more
