R help - Sep 2015 - R lines type in a glm/predict model

Dear Michael! 
Here is my database:  Survival_help.csv
<http://r.789695.n4.nabble.com/file/n4712255/Survival_help.csv>  
That is just what I thought about the point symbols, but is there possible
to put square, circle or whatever instead lines solid, dotted, etc?? 

I draw the graphics with dotted lines, but I want to put squares. 

Thank you very much for you help!!!
Laura

If you do not want point symbols, then you have not explained yourself well. Can
you offer a link to an example in your domain of investigation for "putting
squares" to signify value that would otherwise be represented with a line?
Are you hoping to represent a value by varying the dimensions of a square with
relative proportions of the sides or areas? (This is not generally considered an
unambiguous strategy because of the manner in which humans perceive areas.)

Hey David! 
This is my graphic.  sup.png
<http://r.789695.n4.nabble.com/file/n4712271/sup.png>  
I want only to change the line type (square line instead dotted line) in
order to distinguish the species. 

Thank you very much! 
Laura
