r - Error when using rbind to merge data.tables and one of them is empty -

-

Three (or more) data with RBID. An error is issued while merge Tuberge and an empty data is qualified between two non-empty data. TB: 

  & gt; Loading Required (Data Eligible) Required Package: data.table data.table 1.9.2 for Support Type: Help ("Data Eligible") & gt; DT & LT; - Data suitable (x = c (1,2,3)) gt; RBIDID (DT, Data.W., DT) Error in Setclaimer (TT, CMH (match.name, make name (original.name [x]], (& lt; text & gt; # 1) : The column number is out of new order limits: NA   
 This does not happen when the empty figure is in the end:  
 > RBID (DT, DT, DatataHable ()) x 1: 1 2: 2 3: 3 4: 1 5: 2 6: 3   
 But some other error occurs when empty data Accessible startup:  
  & gt; RBIDID (data) Eligibility in the data (), DT, DT) Data: Rbind.data.table (...) (& lt; text & gt; # 1): In the colnames of some colnames of the argument 2 (x) Are not present 1. If there is a logic colnames they may be in a different order, but they all should be present. Alternatively, you can supply unknown lists and they will be included in the situation or use. Set names = FALSE. However, if we only use two arguments then everything is fine:  
  & gt; RBIDID (Data WABB), DT) x 1: 1 2: 2 3: 3   
 Should the expected behavior be avier?   
 
 
 It seems that due to incompatible behavior in  data.table :: rbind, data. Table . Adding the following line will fix it Please enter a bug-report with  data.table  developers    .... original.names = lapply (list (. ..), name) allargs = lapply (list (...), as.data.table) original.names = root. Name [sapply (allargs, length)> 0L] # This new line is allargs = allargs [sapply (allargs, length)> 0L] ...

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
