[R] Limit on number of Rows when reading R dataset

[Harsh]

Hello,
I am trying to read a dataset with 100,000 rows and around 365 columns
into R, using read.table/read.csv.
In Windows XP, with R 32 bit, I am able to read only 15266 rows and
not more than that.
I tried the same in R running in Ubuntu and it does the same and reads
only 15266 rows.
Using the nrows paramter i can read rows less than 15266, but when i
used a value larger than 15266, it reads only 15266 nevertheless.

Thank you for your patience and responses.
