मेरे पास अल्पविराम से अलग वर्ण वर्ग है 

  ए = "123,456,789"   
 और जब मैं चरित्र वर्ग में आइटमों में से एक को एक वर्ण सरणी में मौजूद होता है, तो मैं तार्किक वेक्टर प्राप्त करने का प्रयास कर रहा हूं।  
  B & lt; - as.array (c ("456", "135", "78 9", "111"))   
 मैं हूं आकार के तार्किक परिणाम की तलाश 4 (बी की लंबाई)  
  [1] सही झूठ सही गलत   
 आर के लिए काफी नया है इसलिए किसी भी मदद की सराहना की जाएगी । पहले से धन्यवाद।   
 
 
 आप sapply और grepl के संयोजन का उपयोग कर सकते हैं, जो मेल खाते के साथ तार्किक लौटाता है < / P> 
  sapply (B, grepl, x = A)

I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ...
