Re: [R] Problem in installing and starting Rattle
I also have the problem trying to start rattle Windows 7 32-bit R 2.12.0 When I try library(rattle) I get an error message The procedure entry point deflateSetHeader could not be located in the dynamic link library zilb1.dll I hit OK and it prompts me to install GTK+ again.

Re: [R] Fetching data
IMO it is not possible. The code behind aspx page queries data from a database server and display it on the webpage.

Re: [R] Problem in installing and starting Rattle
Ok to follow up my post, I finally got rattle and RGtk2 to work. The trick is when R prompts me to install Gtk2+ I still hit yes but after the download, once the installation process starts I close the R Gui window. After Gtk2+ installation is complete I start R again and it worked. -- View this message in context: http://r.789695.n4.nabble.com/Problem-in-installing-and-starting-Rattle-tp3042502p3043318.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
