[R] Graph is without line

[mohan.radhakrishnan at polarisft.com]

Hi,
        Sometimes I get a graph like the attached one. The data type could 
have something to do with it. This graph does not use the color and does 
not draw
a line. Earlier I used to convert the factors in the data frame to another 
data type and drew the correct graphs.

Any idea why this happens ?

Thanks,
Mohan
