similar to: clear screen?

hi, I use R - 2.15(32bit), and want to make a code to clear a console.

Greetings R-ians: Searching the Searchable Mail Archives I discovered that ctrl L will clear the Rgui screen, which is what I'd like to do from a print (or some similar) statement.

Hi,   I'm reading 100s of excel files and many of them contain links to external files (I hate that, but that aside). Every time such a file is opened, a menu pops up asking if I want to update the links. I never want to update the links. I used the macro recorder to see what code would be needed to suppress that message, but to no avail (I tried more variations, but one attempt is shown

Hello, Could anybody offer any advice about implementing a Kohonen self organizing map for categorical data? Specifically I am wondering if there are any pre-existent packages that can deal with categorical data and/or how one would compare the input vector of categoricals with the self organizing map nodes.

Dear R-helpers: I created a folder containing R on a read-only CD and use it by having the R-icon, located on the Windows desktop, point to the CD (R-2.8.1\bin\Rgui.exe) for the "Target," and to a Windows Desktop folder for "Start in." This works nicely EXCEPT that the R help() function cannot display anything, and presents a screen message saying "This program cannot

Dear List, R packages may specify a "LinkingTo" attribute to specify dependencies to the source code (mainly the header files) of other packages. Unfortunately, it is not possible to also have a reference to the generated library (.dll on Windows) of the other package. So including a header file from another package to call an (exported) function will just not help. I've tried

I am having trouble updating packages for R 2.8.1 in Windows XP. Note that I *am* able to update packages for R 2.7.0 (see bottom of posting) so this is not an Internet proxy problem. The steps I took were to (a) Copy over packages from my existing (2.7.0) library subdiretory to the R 2.8.1 library subdirectory. This included a long list of packages including RODBC, rpart, RGraphViz, ggplot2
