Yes, you can, as documented in ?connections, but on the Mac you would have to use: read.delim(pipe(pbpaste)) You can also use pbcopy to copy to the clipboard. Dear R users, I am trying to get data from the clipboard into R on MacOSX. I tried the following, but got an error message:

I think this starts from the position of a batch-oriented package. In R you can refit models with update(), add1() and drop1(), and experienced S/R users almost never use ANOVA tables for unbalanced designs. Rather than fit a pre-specified set of sub-models, why not fit those sub-models that

Dear Amasco, A complete explanation of the issues that you raise is awkward in an email, so I'll address your questions briefly. Section 8.2 of my text, Applied Regression Analysis, Linear Models, and Related Methods (Sage, 1997) has a detailed discussion. (1) In balanced designs, so-called Type

Hi, If I understand correctly the Var(X \hat{\beta}) = X (X'X)^{-1}X' \sigma^2, where X will now be x.pred. Which should be easily obtained by performing the matrix computation and multiplying it with the estimate of the variance. For more details about different aspects of the estimate and

Dear Rense, I already wrote a function, appended below, to compute effects for SEMs, as a method for the effects() generic. I've been thinking about adding this to the sem package, possibly with asymptotic standard errors computed by the delta method, as suggested by Michael Sobel. If I do so, I
