I have a variable that can have either numeric or character values. When numeric, I take one action; when not-numeric, I take another action. Unfortunately, my approaches are awkward, so I look for others' approaches. To detect a numeric value, I have semi-successfully used two appoaches. I somewhat simplify here using direct character values like "123" rather than a variable. 1. !is.na(as.numeric("123")) which responds "TRUE", but !is.na(as.numeric("abc")) responds FALSE #so I know it is not numeric Warning message...

Hi everyone. : ) I meet problem when use form tag in actionmailer. (content-type is text/html, surely) I want to use form action in actionmailer''s view (.rhtml) for some reason. 1. I use start_form_tag helper method as normally, but how I can ? I did <%= start_form_tag :action => "http://myhostname/mycontroller/myaction" %> or <%= start_form_tag :action =>

I'm setting up a new domain with Samba 3.0.30 as the PDC using the tdbsam backend. 'net group' yields an empty list, which is consistent with the cautious appoach that Samba takes: don't do anything automagically. But, a new Windows PDC will come online with several well-known domain users and groups. Did I miss the step where I run some stock script that creates these expected

It makes my code compile and the rest

Hello, I think there's a rather subtle problem with the inst_iterator. It declares its iterator category as std::bidirectional_iterator_tag but C++ standard requirements for forward iterator (which are included in requirements for bidirection iterator), say that the type of expression *r; should be T&, where 'r' is the iterator and T is its value type. The inst_iterator,

How to split HTML content? Well, the text like: <p>Ruby&nbsp;on&nbsp;Rails is a next-generation web-framework<br><b>YEAH!</b>And of course Java killer?! :) &copy;</p> You can split to a pages in a smart way. I tried to realize it in a gem for my internal use, and now when it works for my Rails 3.1.3 application, this is enough to make it public. I

I have to load 10 different data frames and then manipulate those 10 data frames but would like to do this in a more simplified code than what i am doing. I have tried a couple of approaches but cannot get it to work correctly. So the initial (bulky) code is: #Bin 1 #------- #Loads bin data frame from csv files with acres and TAZ data Bin1_main <-
