[R] read.table

I have a question on read.table.

I have a dataset with 273,000 lines and 195 columns. I used the
read.table to load the data into R:
trn<-read.table('train1.dat', header=F, sep='|', na.strings='.')
I found it takes forever.

then I run 1/10 of the data (test) using read.table again. And this
time it finished quickly. So, there might be something wrong in my
data format causing that problem.

then, my question is, is there a way in R to track at which line,
something wrong occurs?
