[R] Generating a binomial random variable correlated with a normal random variable

I am posting this problem again (with some additional detail) as I am stuck and could not get it resolved as yet. I tried to look up in alternative sources but with no success. Here it is:

I need to generate a binomial (binary 0/1) random variable linearly correlated with a normal random variable with a specified correlation. Off course, the correlation coefficient would not be same at each run because of randomness.

If I generate two correlated normals with specified correlation and dichotomize one, the correlation of a normal and the binomial random variable would not be the same as specified.

I greatly appreciate your help.
