I have several dataframes of identical structure. Each dataframe has one
dependent variable and several independent variables. Two different
functions are used to describe the relationships among all the
dataframes. Some parameters that are to be obtained from regression are
shared by all dataframes. Is there a way to do the regression
simultaneously with all dataframes in R? Can nls() do this?
