To reproduce this bug, first go to the website "http://llmpp.nih.gov/DLBCL/" and
download the 14.8M data set "Web Figure 1 Data file". The direct link is
"http://llmpp.nih.gov/DLBCL/NEJM_Web_Fig1data". Save it as "datafile.txt"

Then, start R, type in command "x <- read.table("datafile.txt", header=TRUE,
sep="\t")". The data has 7400 lines, but not all lines could be read in by R.

Easier test data set:
Use the command "head -n 100 datafile.txt > shortdatafile.txt" to extract the
first 100 lines. The R command "x <- read.table("datafile.txt", header=TRUE,
sep="\t")" could not read in even this 100 lines of data. 

But Splus can, with the same command. What is wrong?
