The summary of content
of the output of lm2list().
Arguments
- object
The output of
lm2list().- ...
Other arguments. Not used.
- x
An object of class
summary_lm_list.- digits
The number of significant digits in printing numerical results.
Value
summary.lm_list() returns a
summary_lm_list-class object, which
is a list of the summary() outputs
of the lm() outputs stored.
print.summary_lm_list() returns x
invisibly. Called for its side
effect.
Examples
data(data_serial_parallel)
lm_m11 <- lm(m11 ~ x + c1 + c2, data_serial_parallel)
lm_m12 <- lm(m12 ~ m11 + x + c1 + c2, data_serial_parallel)
lm_m2 <- lm(m2 ~ x + c1 + c2, data_serial_parallel)
lm_y <- lm(y ~ m11 + m12 + m2 + x + c1 + c2, data_serial_parallel)
# Join them to form a lm_list-class object
lm_serial_parallel <- lm2list(lm_m11, lm_m12, lm_m2, lm_y)
