[R] how to do this sum?

[GuangXing]

I am sorry for my ignorance.
table_x is defined as follow:
>table_x<-read.table("stat.txt")
in the stat.txt,there are 5  cols,there are so many big intergers in the every cols.
Now, I want to to that:
>sum(table_x[,3])
But it does not work.
How can I?
Pls help me!

Of course.
table_x means assign x to the function called table.
if you call the table by the name table.x, it will
probably do the job.
