问题 I am having trouble adding R2 annotations to a faceted plot, where my R2 values are sometimes <0.01 (yes, it's not a good regression). I would like the 2 of R2 to be superscript. I have tried several options but seem to be stymied by the < symbol in my values eg, using the iris data set, I first set up a new data frame with my R2 values previously calculated. The x & y positions are also set up as these are different for every facet (not essential for the iris dataset, but it is for mine)

问题 I am unable to get the ExpressionEvaluatingRequestHandlerAdvice class to work in Spring Integration 4.1.x. The following expression advice context XML snippet produces a conversion error stating that Spring cannot convert the property onSuccessExpression to an Expression from a String. Prior to Spring Integration 4.1.0-RELEASE the setOnSuccessExpression() method only accepted Strings, now it is overloaded to accept a String or Expression. <sftp:outbound-channel-adapter channel=

问题 I have a problem with my simple program in assembly. I'm using DOSBox and TASM. The problem is that the operand types don't match in lines 76, 78, and 80. This is after multiplication. I tried to make some changes by using a different variable size. ; -------------------------------------------- ; Equation=(a+c*b)/d-2*c, ; -------------------------------------------- .model small .stack 100h .data a db 0 b db 0 c db 0 d db 0 result1 db ? result2 db ? message1 db "Equation: (a+c*b)/d-2*c a=$"

问题 Before you start criticizing and pointing me §8.7.2 of C# specification, read carefully :) We all know how switch looks like in C#. Ok so consider the class MainWindow with "nasty" Bar method static int barCounter = 0; public static int Bar() { return ++barCounter; } Somewhere in this class we have code like this Action switchCode = () => { switch (Bar()) { case 1: Console.WriteLine("First"); break; case 2: Console.WriteLine("Second"); break; } }; switchCode(); switchCode(); In the console

问题 Note: please pay attention carefully this is not a duplicate. I need to create the following Lambda expression: () => model.property the model and its property will be determine at runtime. I want a function that takes the model and property and generate the expression: public object GenerateLambda(object model, string property) { } If it is possible I don't want the function to be generic. but I think the main problem that I have is with () expression. Update : The return type of
