Data on Sitophilus orizae
Description
s.oryzae is a list of three elements:
$data: 97 measures (in micrometers) of the headcapsule width of rice weevil larvae (Sitophilus orizae) belonging to any of four possible instars.
$mu4: the mean headcapsule width (in micrometers) estimated from 40 fourth-instar S. oryzae larvae. These 40 larvae doesn't belong to the data set s.oryzae$data as stated previously.
$sd4: the standard deviation of headcapsule width (in micrometers) estimated from 40 fourth-instar S. oryzae larvae. These 40 larvae doesn't belong to the data set s.oryzae$data as stated previously.
Usage
data(s.oryzae)Format
The format is a list of three elements:
$data: a vector of 97 numerical values
