r - ggplot2 stat_function - can we use the generated y values on other layers -

-

This question arose when I tried to attract a standard normal distribution with ggplot (easy to do with stat_function) Trying the area under the curve for different quintills -

Enter image details here

I was able to do this with geom_line and geom_ribbon to do a data frame with a range of values ​​for x and the corresponding dnorm value for each x (X = seq (-3,3, length = out), with the "bottom", and 

  data = data.frame (figures, iFeil (x & lefthinum; conomorum (0.2) 1000) Data $ y = dnorm (Data $ x) Data $ Quintil & lt; ifelse (x & lt; qnorm (0.4), "secs", ifelse (x & lt; qnorm (0.6), "middle", ifelse (X & lt; qnorm (0.8), "fourth", "top")))) data $ quintals & lt; - ggplot (data, aes (x = x, y = y, fill = quintile) - factor (data $ quantal, level = c ("bottom", "second", "middle", "fourth", "top")) ) + Geom_ribbon (AES (ymax = y), ymin = 0, alpha = 0.5) + geom_line (color = "black") + theme_bw () + theme (legend.position = "bottom") + Scale_fill_manual (values ​​= C (+ "darkgreen", "red", "purple", "blue", "gray")) + geom_vline (xintercept = c (qnorm (c (0.2,0.4,0.6, .8))) Size = 1) + Scale_y_continuous ("", breaks = NULL) + scale_x_continuous ("", breaks = NULL) , "color" = "c" ("darkgreen", "red", "purple", "blue"), size = 1)  
 I find it more attractive to use stat_function and I think that to plot the line Will have to set a set of y values ​​- I tried to add colorful band to reach them on other layers, but unable to do this - I have to see that someone can explain how to do this or Why can not we?  
 Instead of creating the data itself, in another word, and to use the geom_line to draw the curve, I want to do something like  
 < Code> ggplot (NULL, AES (x = c (-3,3)) + stat_function (fun = Dnorm)   
 and use it to generate data which stat_function generated - I received the value of the generated y value (I tried to use .. ..) Was not able  
 Is there a way to use those values? if so?  
 
 
  ggplot (null, aes (x = c (-3,3)))) + Stat_function (fun = dnorm, geom = "ribbon", mapping = aes (ymin = 0, ymax = .. y .. ..))

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: < P> Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing? Flaffeh said, you have PDO Missing Mysqy, try it: $ con = new PDO ('mysql: host = 127.0.0.1; dbname = csvdangercheck', 'root', '');

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
