मैंने एक डेटा फ्रेम की पहली पंक्ति निकाली है

  & gt; शीर्ष / यूरो तिथि: USD / USD बंद करें USD / JPY बंद करें USD / CHF बंद करें GBP / USD बंद करें EUR / GBP बंद करें EUR / JPY बंद करें EUR / CHF बंद GBP / JPY बंद करें GBP / CHF बंद करें    पहला coulmn है  'दिनांक' , दूसरा कॉलम  'EUR / USD बंद'  और इतने पर ... अब, मैं EUR, JPY, USD, GBP और निकालना चाहता हूं एसएचएफ यानी अलग मुद्राएं मैंने  strsplit ()  का उपयोग करने की कोशिश की, लेकिन यह काम नहीं करता क्योंकि यह डेटाफ़्रेम है।  
 कृपया मुझे और अधिक मार्गदर्शन करें। धन्यवाद   
 
  मैं प्रसाद की टिप्पणी से सहमत हूं। ऐसा लगता है कि डेटा के साथ कुछ भी नहीं है। फ्रेम। ऐसा लगता है कि आप केवल एक चरित्र वेक्टर से चीजों को निकालना चाहते हैं:  
  curr_pairs & lt; - gsub ("बंद", "", शीर्ष_प [1]) unique_curr & lt; - अद्वितीय (सूची ( "एसयूएचएफ़" "जीबीपी"

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!

    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
