Respected Sir,
 
I am working on something in R. I am getting the following error.
 
Warning messages:1: the standard deviation is zero in: cor(x, y, na.method, method == "kendall") 
 
I like to handle this error.
 
I like to know how to do error handling in R. 
 
I want to write the WARNING MESSAGES to a text file and exit R. Please help me with a solution.
 
My mailid is anu1978@hotmail.com
 
Thanking you,
Anusha
