..I'm learning R and Business Statistics at the same time.
..I'm pretty new to R. 
..I'm trying to perform ANOVA.

..I have 3 samples from 3 populations for anova.
..So, I decided to perform anova by doing the following:

	a <- (85,75,82,76,71,85)
	b <- (71,75,73,74,69,82) 
	c <- (59,64,62,69,75,67)



..I got:

"Error in print.anova(a, b, c) : anova object must have colnames(.)!"

	I tried to create colnames, but probably I didn't understand how to do it properly...And I guess my 'approach' to performing ANOVA in R was definitely wrong too.....

..Please, help me with ANOVA. I suspect, it's not that difficult...but still can't figure out how to do it.
..Thanks in advance.

..Best wishes,
