As in the majority of program, if we specify the name of the data set and do not explain to the perform which variables to use, R will generally rely on them all. Right here we utilize the summary functionality to obtain fundamental summary studies.
I have in excess of a hundred model outputs that needed to be saved from Stata. And that i am so grateful to God I discovered your weblog put up. Your log-file technique can be a gem of an idea! Even the Stata complex company didn't tell me that. Would you be producing an update to this write-up, if there are already developments ..?
