r - Error with grid.arrange:input must be grobs -


मेरे पास निम्न आर-स्क्रिप्ट है: 

  लाइब्रेरी (ggplot2) लाइब्रेरी (gridExtra) Sys.setenv (LANG = "en") सी 1 & lt; - ggplot (mtcars, एईएस (कारक (cyl))) + geom_bar () c2 & lt; - ggplot (mtcars, एईएस (कारक (cyl))) + geom_bar () + Coord_flip () grid.arrange (c1, c2, ncols = 1)   
 मुझे ग्रिड के साथ निम्नलिखित त्रुटि मिलती है।  
 
 arrangeGrob में त्रुटि (..., as.table = as.table, क्लिप = क्लिप, मुख्य = मुख्य:: इनपुट grobs होना चाहिए!   
 मुझे पता नहीं लगा कि समस्या क्या हो सकती है। / P> 
 यहां मेरे प्रयुक्त संस्करण हैं:

 मुझे इस विशेष त्रुटि को पसंद आया, यह एक गुपचुप एक है। लंबी कहानी छोटी, पैरामीटर  ncol  है, नहीं  ncols  है। आपके कोड में,  1  को एक प्लॉट ऑब्जेक्ट के रूप में माना जाता है, इसलिए यही विफल रहता है, इसलिए नहीं क्योंकि ggplots अमान्य है त्रुटि संदेश बहुत उपयोगी नहीं है, जो स्थिति को अस्पष्ट करता है। # Ncols = 1 ग्रिड के साथ वही त्रुटि। (सी 1, सी 2, ब्लाह = 1) # दंड ग्रिड। (सी 1, सी 2, एनएलसीएल = 1) # आरजीआर / <>

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

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? ...
