Afte loading MAS, type 'hubers' (without brackets) and look at the code. That

hi guys and gals ... How are you all ...
i have to do something in robust regression by R programm , and i have some
problems as following:
*the first :*
suppose
w(r) =1/(1 r^2) and r <- c(7.01,2.07,7.061,5.607,8.502,54.909,12.222)
and i want to exclude some values from r so that (abs(r)>4.9 ).
