i was going through a tutorial on subsetting... http://www.ats.ucla.edu/stat/r/modules/subsetting.htm why would one name the variable with a dot? like hsb2.small other languages use it to navigate through objects or arrays.. whats it used for in R?
It's just style. Same thing as hsb2_small, but R is so cool that there are no objects or arrays going on here.
By the way here is an outstanding paper by Paul Teetor on how to program in R using functional and vector programming styles to get good performance: http://quanttrader.info/public/FasterRCode.pdf
hey caveman, are you using IBrokers and tws with R to do all of this ? I am actually looking to do the same kind of stuff and wanted to know where you started out with all fo this.
