Suppose I have run the simple linear reggression model through R code based on Data file(name is DATA) which has 30 line data. Now I need plot and run the simple linear reggression model through R code based on same Data file with only 1 to 20 lines data. If I wrote the code : Data2=[1:20], then use plot(), lm(), fit() commands. cant work it How to write the R code for the second simple linear reggression mode ? thanks for your help.
