[R] "Too long to display" problem

[Wuming Gong]

Dear list, 

I used read.xls in gdata package to read a worksheet in which certain
field contains very long character strings (nucleotides sequence,
nchar > 10,000). Then, the values in these fields are automatically
converted to "TOO LONG TO DISPLAY". How can I get those original
characters instead of "TOO LONG TO DISPLAY"?

Thanks,

Wuming
