Re: [R] strange warning message

I get a similar message when i start Sciviews R console. I do not get the message when I start R directly or through Tinn-r . If I load the libraries one by one the message is returned after svViews is loaded. I presume there is some problem with svViews. However it does not appear to have any consequences for my work. I use R 2.3.1 with Windows XP and I should have the latest versions of packages installed

output of R session started with Sciviews R is a collaborative project with many contributors. Type 'contributors()' for more information and 'citation()' on how to cite R or R packages in publications.

Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser interface to help. Type 'q()' to quit R.
