Re adline()

Sure,but my problem is that the script is run from the console
windows,therefore I believe that the cat or readline doesn?t work...

I can't reproduce the error you have. With me, it runs all fine. In
fact, readline apparently flushes automatically, as I didn't have to
use the flush.console() at all.

test.r
-------
cat("1- 24horas\n")
?cat("2- 12horas\n")
?cat("3- 8horas\n")
?selection<-readline(prompt="\nSelecciona numero de horas:")

?if(selection=="1"){
?cat("Selection1\n")
?}
?if(selection=="2"){
?cat("Selection2\n")
?}
?if(selection=="3"){
?cat("Selection3\n")
?}

source("G:/Temp/test.r") # load the saved script "test.r"


You can try to look at ?announce (package odfWeave) instead of cat and
flush.console, but I have the slight impression there is something
else going wrong.

I put that before selection but Nothing happened...I don?t know because
when
I executed the code, in the console doesn?t show cat("1-24hours)...and
neither asked me Select numers of hours from de line or readline...

Hello, I would like to ask you a question.I have a program in R and I
use
the
readline method to ask the user some things,but i don?t use the R
console
but I use Win console then not appear what I put.I put the code as you
look
for:

cat("1- 24horas\n")
cat("2- 12horas\n")
cat("3- 8horas\n")
selection<-readline(prompt="\nSelecciona numero de horas:")

if(selection=="1"){
prediccion=exp(x.reconstruida[1441:1450])
}
if(selection=="2"){
prediccion=exp(x.reconstruida[720:729])
}
if(selection=="3"){
prediccion=exp(x.reconstruida[481:491])
}

write.table(prediccion,"C:\\Temp\\prePrueba.txt",quote=F,row.names=F,append=T,col.names=F)


//end of code.

Excuse me but my English is bad, i hope explained me well,

A greeting,
Ignacio.

I think this is a matter of flushing the console before the readline
call. See ?flush.console
