[R] Character Variable in X axis scatter plot

[David L Carlson]

Function strptime() will convert the date-time character string to a POSIXct
object that you can use in your plot. In general, when posting a query to
r-help:

     1. Do not use html, only plain text (see what happened to 
         your data below.
     2. Use dput() to convert your data to a format that is easy 
          to import from an email message.
