[R] read.table() question

[Susan Lin]

Hi,

In the following code, I got an error meesage if an
input file is empty, and the program stopped running.
Could someone to tell me how to handle this problem. I
want the program to keep running. Thanks.
for i in [1:3]
{  
    file=paste("file", i, ".dat")
    x <- read.data(file)
    x(11)
    plot(x);
    dev.off()

}
