I?ve been using this routine for several years. I?m sorry, I don?t remember where I got it. It works as it should, viz. it blanks the R console. But it requires package rcom and now that requires rscproxy. cls <- function () { require(rcom) wsh <- comCreateObject("Wscript.Shell") comInvoke(wsh, "SendKeys", "\f") invisible(wsh) } > cls()

After installing the package 'rscproxy' downloaded from the CRAN server, I get the following error message from R 2.8.0 about a version conflict : package 'rscproxy' successfully unpacked and MD5 sums checked The downloaded packages are in C:\Documents and Settings\John Meerman\Local Settings\Temp\RtmpbK9mxN\downloaded_packages updating HTML package

" I realise eval (known as execute in one of my other languages) is not a good idea. The background to my question is as follows: Using

Hi, I am running a test to call an R script with in excel using VBA. My VBA code is shown bellow. The middle section of this mail also includes the content of my Rscript.

Is this intentional- I can see some packages like snow and multicore which are desirable but quite optional.(see list

Hello, One of our packages contains C++ code that needs to be compiled against 2 other packages. So the LinkingTo field in DESCRIPTION looks like this LinkingTo: FLCore,FLash Both packages are also in the Depends field.

Hi I'd like to suggest to make R more informative when a user updates a package A where there's at least one package B that has "LinkingTo: A" in its description. To illustrate the problem, assume package A is updated so that its C/C++ header interface (in inst/include) is changed. For package B to pick up these changes, we need to reinstall package A. In extreme cases, if
