Hi R fans
I am trying to make a program to ask the user to choose data file:
print("Choose data file please !")
matr=read.table(file.choose(),dec=".",header=TRUE)
The problem is that the prompt
Choose data file please !
comes after I have chosen the file.
What am doing wrong?
Thanks in a
Using print() for a 'prompt' is rather unusual: people normally use
message() or cat().
You haven't told us your OS, but if this is Windows, see rw-FAQ Q7.1.

You can use
choose.files(caption="Choose data file
please!",multi=FALSE,filters=Filters["All"])
This will show the prompt in the file selection dialog and also allows you
to restrict the list of possible choises with a filter.
