[R] Getting summary.lm to include data for coefficients that are NAs?

Is there a way to get the following code to include liens where the coefficients are “NA”?



Using a loop, I am running regressions on several “subsets” of “data1”.

“reg <- ( lm(lm(data1[,1] ~., data1[,2:l])) )”

My regression has 10 independent variables, and I therefore expect 11 coefficients.
After each regression, I wish to save the coefficients and standard errors of the coefficients in a table with 22 columns.

I successfully extract the coefficients using the following code:

I attempt to extract the standard erros using :



My problem:
For some of my subsets, I am missing data for one or more of the independent variables. This of course causes the coefficients and standard erros for this variable to be “NA”.

Is there a way to include the NA standard errors, so that I have the same number of standard erros and coefficients for each regression, and can then store the coefficients and standard erros in my table of 22 columns?
