Always via logical expressions. In this case you can use the logical expression myDF$b != "0" to give you a vector of TRUE/FALSE B. > On Sep 25, 2017, at 8:00 AM, Shane Carey <careyshan at gmail.com> wrote: > > This is super, really helpfull.

Hi In a controller I have method that is accessed via an AJAX call and will conditionally do: render :nothing => true to test the condition hitting this line I was hoping to do something like: response.should render_template(:nothing) How should I test this behaviour? Cheers Shane

Hi, Lets say this was a dataframe where I had two columns a <- c("<0.1", NA, 0.3, 5, "Nil") b <- c("<0.1", 1, 0.3, 5, "Nil") And I just want to remove the rows from the dataframe where there were NAs in the b column, what is the syntax for doing that?

I saw from the thread "color output" that there is a plan to "align the runner". Is there a place to see what that means? I am just curious. Thanks Shane

Hi, I have a set of x, y points where x represents dates and y actual values. I am trying to plot a line graph of the data with points on top, but R is connecting the wrong points with lines. Does anyone know how I can rectify this. Please see sample below: x= 24/09/2009 09:13 16/10/2009 11:17 24/10/2009 21:43 11/09/2009 18:34 22/08/2009 15:45 10/08/2009 00:30 14/08/2009 14:52 24/09/2009

I want to be able to call an action after performing an edit using the in-place editor macro. I want to update multiple divs so I was thinking about using an RJS template. However, I can''t figure out how to trigger another action after the method created by in_place_edit_for runs. Is there is an option on Ajax.InPlaceEditor where I can inject some Element.update calls? Thanks, Shane

I''ve tried the same code on a couple of different sites and I get the same exception for each. Any pointers or suggestions are appreciated.

Hi Just something that I have been finding very helpful sometimes when I am stuck with "how could I test this?" moments is looking at the Rails test suite. At the moment I am working on testing our custom error_messages_for methods and I have found looking at how the Rails tests in active_record_helper work helpful :-) So just thought I''d share that. Have

Hi! Can anyone tell me how to convert the anova/ancova summary output into a data frame? Thanks! Shane Phillips [[alternative HTML version deleted]]

Make your models feel like they are in high school again. This plugin retrieves the most frequently occurring values for each column. It adds methods of the form most_popular_[pluralized_column_name]. Check out <http://shanesbrain.net/articles/2006/08/04/acts-as-most-popular-rails-plugin> for sample usage. The plugin is mostly just a group_by in disguise. It is probably overkill if you just need to find the most popular items for one column, and probably doesn''t warrant a plugin. But if you are a newbie,...

Shane, Please see my Bug nr 488: https://bugzilla.samba.org/show_bug.cgi?id=4889 I've experienced a few strange things I can't explain. Does the copy go faster when you access an other (random) file on your share? are you able to do make a copy from a share with the client in a vmware session on the same samba server?
