Thank you for all the responses.
The answer is quite simple: add -1 at the right hand side
lm (y~dummy1+dummy2+dummy3-1+x1+x2+...+xn).

This may be a simple question for you.
I need to run a linear regression using lm, but I don't want to have the
intercept
in the regression. Instead, I like to use dummy variables. when I had
both the dummy
variables and the intercept in my regression, I got singularity error.
