Hi, I'm trying to get data from a MS SqlServer database into R, using the RODBC package. The problem I've found is that numeric data from my sql queries is returned with only two decimal digits. After searching...

Para mí StatET (plugin de Eclipse) es insustituible. Cuesta un poco hacerse con el entorno si nunca lo has usado, pero luego tienes toda la potencia del eclipse y sus numerosos plugins. http://www.walware.de/goto/statet Un saludo...
