restovec(response, times=NULL, nest=NULL, coordinates=NULL, censor=NULL, totals=NULL, weights=NULL, delta=NULL, type=NULL)
response
| A matrix or dataframe of response values, a list of vectors of event histories, or a list of one or more column matrices, for each individual, with response values in the first column and times in the second, possibly followed by columns with nesting categories, binomial totals, censoring indicators, and/or units of measurement. For independent responses with one observation per individual or for a single time series, one vector may be supplied (in the latter case, the times must be given even if equally spaced). |
times
| When response is a matrix, a vector of possibly unequally spaced times when they are the same for all individuals or a matrix of times. Not necessary if equally spaced, except if a vector containing a single time series is supplied (if not given in this case, it considers the responses to be independent, not a time series). For clustered data with no time ordering, set to FALSE. |
nest
|
When response is a matrix, a vector of length equal
to the number of responses per individual indicating which responses
belong to which nesting category. Values must be consecutive increasing
integers. This is the second level of nesting, with the individual
being the first level.
|
coordinates
|
When response is a vector, a two-column
matrix giving the coordinates for spatial data.
|
censor
| A vector of the same length as the number of individuals containing a binary indicator, with a one indicating that the last time period in the series terminated with an event and zero that it was censored, or, when response is matrix, a matrix of the same size. For event history data, even with no censoring, an appropriate vector of ones must be supplied. |
totals
| If the response is a matrix of binomial counts, a corresponding vector (one total or one per individual) or matrix of totals. |
weights
|
A vector of frequencies or weights. Only applicable
when response is a vector of independent observations.
|
delta
| The unit of measurement (if not equal to unity), a scalar or a vector. |
type
|
The type of measurement: nominal, ordinal, discrete,
duration, continuous, or unknown. This becomes an attribute of the
response object.
|
restovec
transforms a list of vectors of event histories or of
two or more column matrices with times, response values, and possibly
binomial totals, nesting categories, censor indicators, and/or units of
measurement, for each individual, or a matrix or dataframe of response
values into an object of class, response.
Such objects can be printed and plotted. NAs are removed with
rmna
(where necessary, incoordination with the appropriate
covariates).
Methods are available for extracting the response variable, the times, the nesting variable, and the weights.
