Hi,
I am very new to R so these questions may seem simple!
I have a huge 2 sets of data(matrix 5x20000++) in the following formats ,
for example "data.txt" and "data2.txt":
Date Time X Y
03/03/1983 20:00 0.1 990
I would like to recreate a new matrix which filters through "data.txt" and
"data2.txt" to get something as below :
Date Time X_data1 X_data2
Y_data1 Y_data2
31/12/2000 12:00 2.2 5 0
990
So I basically need :
1) When Date AND Time from data1.txt and data2.txt match, list the
corresponding X and Y values (X_data1,X_data2,Y_data1,Y_data2)
Thank you in advance, and I hope I have been clear enough in my message
