[R] read data from a file and vector expansion

2005-01-24 Thread Cuichang Zhao
hello, 
if i need to read data from a file one line and one how can do?
I am using lines - (input.txt)
so that now the variable lines holds all the data in my file and i am using for 
loop to loop each 
lines[i] to get each line. 
for exmaple, right now my lines[i] = 1 2 3 44  54 23 24
I am wonder how can i get each integer from ines[i], and how can i put each 
ingeter into a vector so that my vector i can hold all the data i want. 
I was thinking using a table to hold my data, but right now i think it is 
impossible because my data file is not in good table format, also my data file 
is too long which is about 60,000 pages. 
 
the second question is that: 
i want to declare some vectors to hold the data that I read from the file, so 
when i read one data from the file then i add one to the vectors. 
Example, if right now I have a vector called v - (10 3 8 5 9), then i have a 
data 23 from the file, how i can add 23 to the vector without changing or 
deleting the previous data in my vector. 
 
Thank you so much for all your help.
