Hi!
I'm starting with ARDUINO YUN, and I managed to execute with some success sketch as the . Now I'm trying to program something like this: http://arduino.cc/en/Tutorial/AnalogReadSerial, but with ARDUINO YUN.
While it is simple, for me it is not so, because I can not understand libraries or functions that should be included in the sketch to read an analog input and vizualizarla in the serial monitor.
Sorry for my english.
Thank you!

Well, that English is not your native language isn't a problem, but you need to understand that you need then be even more descriptive in order to explain us what you issues are/where you are getting stuck.
With the little of information that you have provided, the best guess is that you do not properly understand the the default serial port is used on the Yun for the internal communication between the ATmega32u4 and the MIPS/Linux part and therefor can not be used"as is" from examples that refer to a more "standard" Arduino like an Uno or Leonardo...

/*
AnalogReadSerial
Reads an analog input on pin 0, prints the result to the serial monitor.
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
This example code is in the public domain.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1000); // delay in between reads for stability
}
I think the same, I still do not fully understand what concerns the internal communication of Arduino, but I am eager to learn and I have been reading a lot, but I have not progressed far enough.
Going back to the topic, I do not know what considerations should have (or failing that should change in the sketch ) to continue printing the voltage at the Serial Monitor, obtained in the A0 pin of ArduinoYun.
I thought it was a good starting point, since it is only sampled and transmitted. In the future I have the intention to collect data from a sensor and transmit them to PC (maybe this helps you understand this step and the next thing I will do.)
I just want to show on the screen the data obtained by the analog input, I do not know if it's the right way through the serial monitor, or the most convenient way is through the console or a browser.
I hope I have been more explicit
