Hi all,
I am doing analysis which involves fitting a line on trellis plot. The
factor is month. As you know a year has 12 months and I expect to get
12 lines one for each month. I am getting the following results which
is different to my expectation. Am I have to do anything about the
data? Any suggestion is welcome. Thanks.
Call:
lm(formula = curr_data[[tmin_col]] ~ curr_data[[year_col]] -
1 | curr_data[[month_col]])
Residuals:
