Re: [R] Good Programming Practice Question - Functions in Different Files
Hi, I always use source for this kinds of things. If you have a lot of code, you could consider wrapping it into an R-package. This would allow you to load all the code by using the library(myPackage) command. But this might be unnecessary for your situation. cheers, Paul Jason Rupert wrote: I've gotten to the point wih an R script where I would like to encapsulate several blocks of codes in R functions. In order to keep the top level script simple I would like to put them in a separate file. This should help the readability of the top level main script. Is source(...) the best way to load those functions in the top level script? For example, in the top level script Line# 01 source(FunctionsFile.R) 02 03 callfunctionfromfunctionfile(...)

Sundar Dorai-Raj taught me to do the following: Rdir - c:\appropriatepath\R Rfiles - dir(Rdir, pattern='\\.R$', full.names=TRUE) invisible(lapply(aTR, source)) The invisible suppresses the garbage while still displaying error messages. Hope this helps. Spencer Paul Hiemstra wrote: Hi, I always use source for this kinds of things. If you have a lot of code, you could consider wrapping it into an R-package.
