Tena koe Pragya It is advisable to use the extractor functions where they are available; i.e., coef(j) and coef(j)[1] or coef(j)['(Intercept)'] for the intercept.
However, j$coefficients["(Intercept)"] does give you what I suspect you want. Check its structure: str(j$coefficients["(Intercept)"]) and you'll see it is 191.9161 with a name attribute. Thus you can use it 'for other purposes'. HTH ....

My command is j=lm( Y ~ Sex + begsal + time + int) Call: lm(formula = Y ~ Sex + begsal + time + int) Coefficients: (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 (Intercept) 191.9161 How can I get just the value 191.9161? Please help.
