check.SamSPECTRAL.input {SamSPECTRAL} | R Documentation |
The input to SamSPECTRAL should be a numeric matrix WITHOUT any NA, NaN, and +/- Inf. This function checks the input matrix and prodeuces an error for an inappropriate input.
check.SamSPECTRAL.input(data.points,dimensions=1:ncol(data.points),replace.inf.with.extremum=FALSE)
data.points |
A matrix that contains coordinates of the data points. |
dimensions |
A vector that determines which dimension of the data point matrix are chosen for investigation. |
replace.inf.with.extremum |
If TRUE, the Inf and -Inf values will be replaced by maximum and minimum of data in each direction. |
Returns a list with the following entries:
data.matrix |
The data with infinite elements fixed if |
dimensions |
All the checked dimensions. |
infinite |
Will be TRUE if data contained infinite entries. |
