Hi, I would like to estimate something like y = a + b*d2*y + c*d3*y where the dummies are created from some vector d with three (actually many more) levels using factor(). But either there is included the variable y or d1*y. How could I get rid of these? Example: x = c(1,2,3,4,5,6,7,8) y = c(3,6,2,8,7,6,2,4) d = c(1,1,1,2,3,2,3,3) fd = factor(d) lm(x ~ fd*y) gives: Coefficients: (Intercept)

Dear all I am trying to use the cov function in the stats library. I have no problem using this function from the console. However, in my R script I received a "function not found" message. Then I called stats::cov(...) and received an error message that the function was not exported. Then I tried stats:::cov (three colons) and received the error Error in get(name, envir =
