similar to: Help with charting time in seconds as HH:MM:SS on charts

Hello, I am dealing with data stored in a database as a 'time' object. I export the data from the database to a text file and utilize the 'time_to_sec()' function of the database to convert the human readable time (HH:MM:SS) to seconds so that I can use R to do analysis and create charts of the data. I do not need or use days or dates in the data, and the data range is from

Hi all, I need to compare between times and put all similar times in specific 1 minute bins. Unfortunately the original data include seconds as well. My data is in HH:MM:SS format but I need it rounded to only HH:MM and trying in Excel to display "unique" records only does not work since the seconds are not unique. Is there an easy way using perhaps CHRON to change all from the

I have a time tracking app where (pseudo-code) Client has_many Task has_many TimeRecord TimeRecord start_at, :datetime end_at, :datetime What I''m trying to do (and I have done using find_by_sql in the past) is get a sum of the timespan given by ended_at - begun_at for each client.

This is related to my post about .chm where vitamin set me on the right path. http://forum.winehq.org/viewtopic.php?t=1026 Since then I reinstalled Ubuntu 8.04 and wine.

Hi- I need to create simple charts on the fly - I had used JFreeChart in the past with inJ2EE apps. Is there any equivalent here for Ruby. My charting needs are simple: just line charts.

Hi, what would be a good way of enhancing the ancova function from the HH package when using a 2 factor ANCOVA? The current behaviour for the "ancova" function from package HH is: ---------------------------------------------- | P1 || P1 || P3 || P4 | | PS | <- the lattice strip ---------------------------------------------- | x|| x ||x ||x | |

I would like to be able to start the Wine .chm file-viewer, C:\windows\hh.exe, from the command-line like this: wine hh.exe /some/dir/somefile.chm It works if the current directory contains the .chm file, but not if I have to specify a path. Am I missing something?

Hi, As a long time Java/J2EE exponent I wanted to give Rails a fair crack of the whip and after we evaluated it for several weeks I have to say I like it. The installation process for the base system/framework is straightforward on the two platforms we''ve tried (Windows and Mac OS X). However, the charting components available, relying on ImageMagick or GraphicsMagick seem less clear
