I am a very new R user. I am trying to write functons and debug functions. One problem for me is that I need to alwasy copy the whole function body and resubmit to R console every time I changed even one line of the function. Because I have long algorithm function, copying and pasting is very tedious for me. I assume if I save the function files, R should be able to just use the new function body since it is a scripting language. Can somebody let me know his best practice of using R function? -- View this message in context: http://r.789695.n4.nabble.com/r-function-definition-tp4651943.html Sent from the R help mailing list archive at Nabble.com.

You might be at the point where a development environment is useful. There are multiple choices, but I'm quite fond of RStudio. http://www.rstudio.com/ide/download/ Rob

Are you using windows? If you are you may want to try to run your R code from a batch file:
REM on Microsoft Windows (adjust the path to R.exe as needed)
"C:\Program Files\R\R-2.13.2\bin\x64\R.exe" CMD BATCH "C:\Users\Frank\Documents\R\Projects\Heinrich\Heinrich.txt" "C:\Users\Frank\Documents\R\Projects\Heinrich\Heinrich.out"
PAUSE
Where ...Heinrich.txt is the following R code in a text file:
pdf("Heinrich.pdf")
## load Pearson package
library(PearsonDS)
## calculate probability density function Fig. 1
x <- seq(0.0, +20.0, length=100)
hx<- dpearsonIV(x,m=2.25,nu=5,location=17,scale=2)
k<-0.0206631
plot(x, hx , type="l", lwd=2, tck=1, xlab="x value", ylab="Density", main="J. Heinrich Fig. 1")
## calculate probability density function Fig 2
hx<- dpearsonIV(x,m=0.75,nu=1.0,location=15,scale=0.5)
k<-0.218991
plot(x, hx , type="l", lwd=2, tck=1, xlab="x value", ylab="Density", main="J. Heinrich Fig. 2")
quit()
and Heinrich.out will contain the output of the results of the commands. Look at Heinrich.out for results and errors. Then correct the text file and rerun.
