GoogleVis on shiny in R -

I have the following code for my data set, Det,

ui.R 

  Library (GoogleVis) Library (bright) Shainiuai (Flippej (Shirshkpanel ( "visualization tools"), Saidbarleaut (# Hederpanel ( 'data selection'), Saidbarpanel (Cyninput ( 'x', 'x variable' option = c ( "demand", "capacity Waik", "Sttetl", "Nutetl")), select the input (Y, Y variables, options = C ( "demand", "capacity and Aik "," Sttol "," Select 'input' ( 'W', 'size' option = C ( "demand", "potential Wyk", "Sttol", "Nutol")), select the input (Z 'color' option = C ( "physical", "Nurse Practors")), Detrenj input ( "Date" label = H 3 ( "date range")), Mukypanel (htmlOutput ( "plot"))) )   
 server.R  
  Library (bright) Library (GoogleVis) ShinyServer (function (input-output) {datasetInput & lt; - reactive (% Diff $ position% IN% input $ position,]}) Output $ chart & lt; - Rand Plot ({M & lt; - Jivismoshnchart (DT, Aidivr = "clinic", Taimwayr = "date", xvar = inp Ut $ x, yvar = input $ y, color = Input $ z, size = Input $ w) Plot (M)})})   
 This does not give me an error but it is not a conspiracy to speed chart. Please tell me what is wrong with this code.  
 
 
 In the  server.R  file.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
