...87CW(Default8087CW); 3. The following function may be useful in debugging; it returns false when the control word has been unexpectedly changed: function Okay8087CW:boolean; begin result := ((Default8087CW xor Get8087CW) and not $E060) = 0; end; Thanks.

...port library for using dll. Following the instruction in the readme.package, I used the command “lib /def:R.exp /out:Rdll.lib”, however, the error message showed “Cannot open file R.exp”. I downloaded the source code R-1.9.0.tgz, but I can not find R.exp. Thanks!

...e routine in the local directories of this function (or package). Second, if I found the routine, could I call it just like this way, say, fit <- .C("lasso", …,PACKAGE = "lasso2") in my own functions. My system is Windows98 with R1.80.

...3. After I copied the R.exp to C:\ and run “lib /def: R.exp /machine: ix386 /out: Rdll.lib”, the error message showed “Cannot open Rdll.lib” 4. I am not clear about “add Rdll.lib to the link command or add it to the libraries to be used in the IDE”.

Dear R community: I want to simulate a regression matrix which is generated from an orthonormal matrix X of dimension 30*10 with different between-column pairwise correlation coefficients generated from uniform distribution U(-1,1). Thanks in advance! Rui [[alternative HTML version deleted]]

Dear R community: I am trying to do a simulation study mentioned by Fu (1998), Journal of Computational and Graphical Statistics, Volume7, Number 3, Page 397-416. In order to give a clear statement of quesion I copy the following paragraph from the article: We compare the bridge model with the OLS, the lasso and the ridge in a simulation of a linear regression model of 30 observations and 10
