Limit on number of Rows when reading R dataset
Thank you Uwe and Prof. Ripley. The problem was solved. The row in question indeed have garbage data, which possibly was truncating the number of lines read. I apologise for the oversight. Thank you once again. Regards Harsh Singhal Bangalore, India

Take a look at your dataset at around that row. Perhaps you have an unmatched quote? The limit on the number of rows of a data frame is far larger than 100,000 (2^31-1, but you will run out of address space on a 32-bit platform before that - see ?"Memory-limits"). On Tue, 2 Dec 2008, Harsh wrote:
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.
