r - dplyr::manip: How to use string arguments (holding colnames) instead of column names -


I like the description of the headline:

instead: 

 < Code> Filters (mtcars, cyl == 8) I  
  var  
 
 such as 
 
  mtcars [Joe (mtcars [, var] == 8],]  
 
 I think there are functions like  starts_with ()  but none of IMHO In fact, it is not suitable for the above mentioned rather than simple application.

try this: 

  mtcars%>% (filter (.,. [[Var]] == 8))

java - Joda Time Interval Not returning what I expect -

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
