Creates a list of sparse data from a matrix
Creates a list with sparse data from a matrix that has NAs. The length of the list will be equal to the number of columns in the data matrix (replications)
sparse.list(data,time)
data |
If the set is supplied as a matrix object, the rows must correspond to argument values and columns to replications, and it will be assumed that there is only one variable per observation. If y is a three-dimensional array, the first dimension corresponds to argument values, the second to replications, and the third to variables within replications. |
time |
Time points where the observations where taken. |
a list with length dim(data)[2]. Each element of the list is a matrix with ncol > 1. The first column of each element corresponds to the point index per observation.
