[R] Error Message when running Linear regression

[sportsguy]

Win 7 x64 R x64  8 Gigs RAM

Data is 1,000 rows, 40 variables
regression is with 3 variables. . .   this doesn't appear to be big to me. .
. 

results = lm(Est_Margin ~ Est_Material + Est_Labor + Est_Subcontractor,
data=NorthEast)

error msg:
Warning messages:
1: In model.response(mf, "numeric") :
  using type = "numeric" with a factor response will be ignored
2: In Ops.factor(y, z$residuals) : - not meaningful for factors
----------------------------------------------------------------------

any help with the interpretation would be greatly appreciated. . 
not sure why the numeric unless the file didn't import the data correctly. . 

thanks in advance
