hi ,when i read a lots of files

for (i in 1:totnum)
{
cop_x_data<-read.table(flnm[i],skip=2)
if(i==1) {cop_data=cop_x_data}
else {cop_data=rbind(cop_data,cop_x_data)}
}

some of the files are missing . so this loop can not go on .I wonder how can
I go on
 the loop cycle while reading the files just like the command
read(unit,err=linenum) in fortran ?

thank you .
