unable to move temporary installation of package
Do you have other instances of R open at the time you are doing this? Did you already have mgcv installed in your personal library when you tried installing it again? There is clearly something preventing you from writing to your library, or at least to specific packages in your library.

How to get predicted values of y for different x values?
Here is my model with interaction terms and control variables (I changed variables names for easy read): reg1 <- lm(y ~ x1*x2*x3 +control1 + control2 + control3) x1 ranges from 0 to 6; x2 from 0 to 5; and x3 from 0 to 4. All three are discrete ordinal variables; but I will treat them as continuous variables. (a) How can I see the predicted values of y for each of these scenarios (210

My R code is not efficient
Dear R users, I have two n*1 integer vectors, y1 and y2, where n is very very large. I'd like to compute elbp = 4^(y1) * 5^(y2) * sum_{i=0}^{max(y1, y2)} [{ (y1-i)! * (i)! * (y2-i)! }^(-1)]; that is, I need to compute "elbp" for each (y1, y2) pair. So I made R code like below, but I don't think it's efficient Would you plz tell me how to avoid this "for"

7 days confusion over lists

R CMD SHLIB with ifort
Hi, I am running Linux (64 bit) R, compiled under gnu compilers. I am looking to compile a Fortran program with the ifort (the intel compiler) and then be able to import that as a library into my version of R.

Rcpp and mclapply
Dear all, I have an R script that uses Rcpp, and I have been trying to parallelize it using mclapply (I tried with the multicore and the parallel library) Sometimes (not always, interestingly), the CPU use for each core drops, usually so that the total over all cores reaches 100%, i.e., as fast as if using just one single core fully. I tried my code directly from within emacs, and also using a

Rodbc quesion: how to reliably determine the data type?
Hello, How can I tell RODBC to scan all the records of an xls file to determine the data type? If the first n records happen to be empty Rodbc assumes a character, and any numbers are made <NA>. And if, for instance, the first n records contain numbers, and later they also contain characters, those characters become NA. Cheers!! Albert-Jan
