It is advisable to use the extractor functions where they are available; i.e., coef(j) and coef(j) or coef(j)['(Intercept)'] for the intercept.
However, j$coefficients["(Intercept)"] does give you what I suspect you want. Check its structure:
and you'll see it is 191.9161 with a name attribute. Thus you can use it 'for other purposes'.

Subject: [R] Accessing coefficient values in linear regression
I am fitting a simple linear regression model in R. My
command is j=lm( Y ~ Sex + begsal + time + int)
lm(formula = Y ~ Sex + begsal + time + int)
(Intercept) Sex begsal time int
191.916 -241.805 3.969 5.003 3.040
Now I wish to access the values of these coefficients for other purposes
and all this I need to be done within a code. Using
j$coefficients["(Intercept)"] gives me
How can I get just the value 191.9161?
