this question has answer here: how join (merge) data frames (inner, outer, left, right)? 12 answers i have 2 dataframes df1 , df2. both have common identifier column. df1 has unique lines each identifier. has identifier values not in df2. df2 has multiple lines each identifier value. i want merge 2 preserve number of rows of df2, map (repeating) relevant id rows df1 df2. is best use merge or join or else? arguments? thanks :) without input data, hard provide working code. but, dplyr package's join functions super efficient kinds of joins. in case, can try like: library(dplyr) newdf <- left_join(df1, df2) this keep id's in df1, while retaining duplicate rows in df2 long common column filed matches.

i trying communicate arduino using python. able connect using serial module. code: import serial while true: print "opening port" arduinodata = serial.serial("com7", 9600) print "the port open" while (arduinodata.inwaiting()==0): #i wait data print "there no data" print "reading data" arduinostring = arduinodata.readline() print arduinostring it seems hanging when want read data, in line says arduinostring = arduino.readline() . what problem? instead using while loop inside of main while loop can use if else statement. also, read data can use read function arduinodata.inwaiting() paramater : arduinodata.read(arduinodata.inwaiting()) . hope code you: arduinodata = serial.serial("com7", 9600) while true: if arduinodata.inwaiting() > 0: # check if there data available print "reading data" arduinostring = arduinodata.read(arduinodata.inwaiting()) '...

i wanted know different between connectivityaction , action_state_change. at moment, having broadcastreceiver listen connectivityaction check wifi enable/disable state. in addition, used connectivityaction listen bluetooth enable/disable state. in action_state_change, can same detect enable/disable bluetooth checking intent state_on. the difference have between connectivityaction , action_state_change is: when register connectivityaction in onstart , unregister in onstop in activity, when user select enable/disable in setting screen, receiver still receive message. on other hand, if used action_state_change, if user select enable/disable in setting screen, broadcast receiver action_state_change won't receive message. what different between 2 action filter. connectivity_action - change in network connectivity has occurred. action_state_change - broadcast action: state of local bluetooth adapter has been changed. the first applies network change, second ...
