HI All
I am newbie to using socket in R.
I wrote the function below in R for Windows.
The strange behavior is that each time I call this function R seems to hang
for I don't know what reason.
If I give at prompt line by line the commands below everything is fine:
connection happens immediately, and also reading data from the socket with
valid data.
If I pack these line into a function R starts freezing, connection doesn't
occurr immediately and so the following reading from the socket.
The very strange thing is that this weird behavior goes away once I remove
the read.socket calls. If there are not present; when I do this the
connection happens immediately, but with read.sockect everything hangs.
Can you help me?
Thanks
TestConnect<-function(){
print ( "start" )
aClient=make.socket( host="1.2.3.4", 11111, fail=TRUE, server=FALSE )
on.exit(close.socket(aClient))
print( "connected" )
data = read.socket( aClient, loop=FALSE )
print ( "read" )
print( data )
data = read.socket( aClient, loop=FALSE )
print ( "read" )
print( data )
}
