Hello I am searching for a graph for finding the patterns in writing of Authors. I have around 8 to 10 Authors for whom we have tabulated their writing times. for e.g the data is as follows: Author TimeofWriting A 2009-09-16:57:35:45 A 2009-10-10:09:41:15 A 2009-10-11:15:35:22 B 2009-09-01:06:35:45 B 2009-11-01:13:25:54 C 2009-09-01:17:45:35 C 2008-09-01:20:06:17 I have to draw a graph using ggplot2 or rggobi for finding that how often these Authors writes, how frequently they write.... The data table is of 150 rows. Thanks in advance.
