[R] Re : A smal fitting problem...

May be you are also not familiar with statistic. the solution of
    min \sum_{i=1}^{n} (y_{i}-b)^{2} is the mean. So the solution is  
b<-mean(y)

Dear R-helpers,

I'm for sure not familiar with R, but it seem like a nice sofware tool,
so I've decided to try using it.

Here is my problem I just can't figure out:

I'd like to do least square fit of a straight horizontal (a = 0) line y
= ax + b through some data points

x = (3,4,5,6,7,8)

y = (0.62, 0.99, 0.83, 0.69, 0.76, 0.82)

How would i find b?????

All the best,
Ked
