Description
scarabee.read.data
is a secondary function called at each
scaRabee run. It reads and processes the data contained in the specified
data file.scarabee.read.data
is typically not called directly by users.
Usage
scarabee.read.data(files = NULL,
method = NULL)
Arguments
files |
A list of input used for the analysis. The following elements are expected and none of them could be null:
|
method |
A character string, indicating the scale of the analysis. Should be 'population' or 'subject'. |
Value
Return a list with 2 levels:
- data
A list which content depends on the scope of the analysis. If the analysis was run at the level of the subject,
data
contains as many levels as the number of subjects in the dataset, plus theids
level containing the vector of identification numbers of all subjects included in the analysis population. If the analysis was run at the level of the population,data
contains only one level of data andids
is set to 1.Each subject-specific level contains as many levels as there are treatment levels for this subject, plus the
trts
level listing all treatments for this subject, and theid
level giving the identification number of the subject.Each treatment-specific levels is a list containing the following levels:
- cov
mij x 3 data.frame containing the times of observations of the dependent variables (extracted from the TIME variable), the indicators of the type of dependent variables (extracted from the CMT variable), and the actual dependent variable observations (extracted from the DV variable) for this particular treatment and this particular subject.
- cov
mij x c data.frame containing the times of observations of the dependent variables (extracted from the TIME variable) and all the covariates identified for this particular treatment and this particular subject.
- bolus
bij x 4 data.frame providing the instantaneous inputs for a treatment and individual.
- infusion
fij x (4+c) data.frame providing the zero-order inputs for a treatment and individual.
- trt
the particular treatment identifier.
- new
A logical indicator defining whether or not a modified data file has been created based upon the original file. This is the case if and if only the time of first data record for one or more individuals in the original data file is not 0. The new data file is created such as the TIME variable is modified so that time of the first data record for all individuals is 0; the time of later records is modified accordingly.
