[R] list to matrix

[PIKAL Petr]

Hi

Do not post HTML. Why you did not populate your list directly with coefficients by let say coef(lm.result)?

Anyway, you can reveal structure of individulal list component by str(your.object[[1]]). After that you can extract coefficient component and use sapply/lapply probably with rbind.

maybe

sapply(lapply(your.list, coef), rbind)

can do it.

Petr
