R help - Aug 2007 - Is there any good tools to facilitate us to create R functions?

Dear R users,
  We have some programs for the specific task in our research, but they were
very commonly used. We want to make some functions for them, anybody can
recommend any good tools to facilitate us to create R functions even without
going deep into the theories of R functions ?
  Any suggestions or help are greatly appreciated.

The tool is a) a manual, b) your eye, and after that c) your keyboard.
So, what is your "program" if it is not a function?
If my guess is right and your programm is a sequence of many lines of R 
code: given you have a program that calculates the square root of x, then

myfoo <- function(x){
	sqrt(x)
}

is your function:

myfoo(4)

Hello Zhijie,

You can many specific commands and tricks by using R commander's menus:

install.packages("Rcmdr")
library(Rcmdr)


However, I can not stress enough that if you want to be proficient and 
sound in your work with R, you will have to invest time reading the 
documentation (see documentation section here http://www.r-project.org/) 
and perhaps an introductory book such as the ones recommended in the R 
project site.

Good luck!

Your question is well un-defined. Specify your question, maybe by an
example so we can help.

You can also send me personal email if you want. I graduate from Fudan
too, so I would like to give a favor, lol

Best,

Weiwei
