Functions colSums(), colMeans(), rowSums(), and rowMeans() for hyperSpec Objects

Source: R/colMeans.R

hyperSpec objects can use the base functions base::colMeans(), base::colSums(), base::rowMeans() and base::rowSums().

# S4 method for hyperSpec
colMeans(x, na.rm = TRUE, ..., label.spc)

# S4 method for hyperSpec
colSums(x, na.rm = TRUE, ..., label.spc)

# S4 method for hyperSpec
rowMeans(x, na.rm = TRUE, ..., label.wavelength)

# S4 method for hyperSpec
rowSums(x, na.rm = TRUE, ..., label.wavelength)

Arguments

x

hyperSpec object
na.rm, ...

further parameters to the base functions

na.rm defaults to TRUE for hyperSpec objects.
label.spc

labels for the intensity axis for loadings-like (col) statistics
label.wavelength

labels for the wavelength axis for scores-like (row) statistics
