ncol: The Number of Rows (Spectra), Columns, and Data Points per
Spectrum of an hyperSpec Object)
Description
nrow yields the number of rows in x@data, i.e. the
number of spectra in the hyperSpec object.
ncol returns the number of columns in x@data. I.e. the
number of columns with additional information to each spectrum
(e.g. "x", "y", ...) + 1 (for column spc containing the spectra).
nwl returns the number of columns in x@data$spc,
i.e. the length of each spectrum.
dim returns all three values in a vector.
Usage
## S3 method for class 'hyperSpec':
ncol(x)
## S3 method for class 'hyperSpec':
nrow(x)
nwl (x)
## S3 method for class 'hyperSpec':
dim(x)
Arguments
x
a hyperSpec object
Value
nrow, ncol, and nwl return an integer.
dim return a vector of length 3.
