[R] Problems with large data frames?

I recently added another 1,000 observations to a data frame I have for  
a total of 10,861 observations.  Observations are by row and the frame  
has 15 columns.  R now keeps converting certain columns to factors  
whenever I run regressions and can't seem to figure out the correct  
scaling for the axes of plots on its own.

Are these problems the result of the size of my data frame or  
something else?  I can't see anything wrong with the data itself.  Any  
ideas what might be causing these recent problems and any way to force  
R not to convert variables to factors?
