help in fitted values in lm function

Hi,

I have a data set of 10000 rows and ran a linear regression by using the
function lmres = lm(formula,data)

then got the fitted value by using the value fit=fitted(lmres).

but the number of rows in the fitted one is about 9548,

What could be the reason for reduction in the number of rows in the 

one
