Re: [R] How to catch data from the different dataframes and lm problem?

gression. For example, I used the “regression” function of Microsoft Excel 2003 and intercept is -0.01894 and X is 0.185758. I think that if I can catch “test” (Y) values and “concentration” (X) values into a dataframe, then I can use “lm” to fit linear models. So, how to catch all “test” values fro
