r - Warning in install.packages : cannot open: HTTP status was '404 Not Found' -


मैंने आर पैकेज memoise डाउनलोड करने का प्रयास किया है: 

  Install.packages ("memoise")   
 हालांकि, मुझे निम्न त्रुटि संदेश प्राप्त हुआ है:  
 
 कोशिश कर रहा यूआरएल '' चेतावनी में install.packages: नहीं कर सकता ओपन: HTTP की स्थिति '404 नहीं मिली'। डाउनलोड में त्रुटि। फ़ाइल (यूआरएल, डिस्टफ़ाइल, विधि, मोड = "wb", ...): '' चेतावनी को इंस्टॉलेशन.packages में नहीं खोल सकता है: पैकेज का डाउनलोड '' ?? memoiseâ ???? असफल `  
 मैं इंटरनेट और WWW से जुड़ा हूं। इसके अलावा, मैं एक कार्य नेटवर्क से कनेक्ट हूं। मैं RStudio IDE का उपयोग कर रहा हूँ।  
 क्या किसी के पास इस समस्या का निवारण करने के लिए कोई सलाह है?   
 
 
 के रूप में मैं देख सकता हूँ कि" memoise_0.1.zip "नहीं है हालांकि, "memoise_0.2.1.zip" फ़ाइल है।  
 RStudio IDE का कौन सा संस्करण आप उपयोग कर रहे हैं? क्या आपके पास पहले से स्थापित मेमोरी है? शायद आपको मेमोइज़ पैकेज को अपडेट करने का प्रयास करना चाहिए।

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
