| dimnames {hyperSpec} | R Documentation |
rownames yields the names of the rows (spectra) of a hyperSpec object,
colnames the names of the data colums, and
dimnames both together with the names of the wavelengths (see
below).
## S4 method for signature 'hyperSpec': colnames(x, do.NULL = TRUE, prefix = "col") ## S4 method for signature 'hyperSpec': rownames(x, do.NULL = TRUE, prefix = "row") ## S4 method for signature 'hyperSpec': dimnames(x)
x |
a hyperSpec object |
do.NULL, prefix |
handed to rownames and
colnames, respectively. |
dimnames returns in element wl the colnames of the spectra
matrix, not the values.
The replacement functions for column and row names are used like:
colnames (x) <- value rownames (x) <- value
If changing the colnames, be careful not to touch spc. Otherwise
an error about an invalid hyperSpec object results.
rownames and colnames return an character vector,
dimames returns a list with elements row, data, wl with the
respective character vectors.
