I tried command as.numeric(Qty) #converting column"Qty" in object "demand" to numeric. However it remains a non-numeric value. What is the best way to convert a column of data to a numeric value in R? What is the best way to convert dates into a numeric format (or some format able to be used in an x,y scatter) while still maintaining its inherent "date" property?

Dear, I need to analyse reaction time. The general idea might be described as this: There are 8x8 circles. My program light a circle at one time. The subject then click the lighted circled as fast as possible. After the correct circle is clicked, then the next circle will be lighted for the subject to click on, and so on. My questions are: 1. May I use Time Series Analysis? I read that Time

I''m seeing odd behaviour when I create a ZFS raidz pool using three disks. The output of "zpool status" shows the pool size as the size of the three disks combined (as if it were a Raid 0 volume). This isn''t expected behaviour is it? When I create a mirrored volume in ZFS everything is as one would expect the pool is the size of a single drive. My setup: Compaq

This page for Chinese http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.2/Chinese It is better to name this page to traditional_Chinese. I will do the Simple_Chinese page for this one. These two different Chinese languages,traditional Chinese is used in Taiwan China and simple Chinese used in Mainland.

I believe ZFS is causing a panic whenever I attempt to mount an iso image (SXCR build 39) that happens to reside on a ZFS file system. The problem is 100% reproducible. I''m quite new to OpenSolaris, so I may be incorrect in saying it''s ZFS'' fault. Also, let me know if you need any additional information or debug output to help diagnose things.
