Hi guys,

My concern is to create an automated process from the beginning to the end. I 
want to copy all my code together in one piece and paste it to R console and sit 
back and relax :) except one moment in which the program should ask me to enter 
a number.. and only then (only after getting a valid number from me) it should 
continue to read and process the rest of the code. I tried lots of things 
(readline, readLines, scan, interactive, ask, switch,...) and read manuals and 
searched help forums.. I found several similar questions but never a satisfying 
answer.. so now it became a challenge.. any idea how to overcome this problem (R 
2.11.1 for Windows)? (an example code is below) 

Best,
Fatih



library(gtools)
library(YaleToolkit)
library(xts)
 
### start of my wrong function! 
f<-function(w){
 w<-readline("which data? ")
 w<-as.numeric(w)
 ifelse(is.numeric(w)=="TRUE", w, f())
 }
f()
##### end of my wrong function

v<- ## and output of my function should be a "v" for example which I can use it 
in the next line (v<-w  or something like that??)
 
##the rest works fine
p<-paste("t", v, ".txt", sep = "")
t<-read.table(p, header=FALSE, sep="\t", dec=",", 
blank.lines.skip=FALSE)
rownames(t)<-as.Date(t[,1],"%d.%m.%Y")
colnames(t)<-c("date","start","high","low","end","w.average","lot",
"volume")
x<-as.xts(t) 
whatis(x)
