kernel-class function

An S4 class representing a kernel matrix calculated for a pathway

An S4 class representing a kernel matrix calculated for a pathway

show displays the kernel object briefly

summary generates a kernel object summary including the number of individuals and genes for the pathway

plot creates an image plot of a kernel object class

## S4 method for signature 'kernel'
show(object)

## S4 method for signature 'kernel'
summary(object)

## S4 method for signature 'kernel,missing'
plot(x, y = NA, hclust = FALSE, ...)

Arguments

• object: An object of class kernel
• x: the kernel object to be plotted.
• y: missing (placeholder).
• hclust: logical, indicating whether a dendrogram should be added.
• ...: further arguments to be passed to the function.

Slots

• type: A character representing the kernel type: Use 'lin' for linear kernel, 'sia' for the size-adjusted or 'net' for the network-based kernel.
• kernel: A kernel matrix of dimension equal to the number of individuals
• pathway: A pathway object

Examples

data(gwas)
data(hsa04020)
net_kernel <- calc_kernel(gwas, hsa04020, knots=NULL, type='net', calculation='cpu')

show(net_kernel)
summary(net_kernel)
plot(net_kernel, hclust=TRUE)
