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।

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.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
