col_by_value: col_by_value

In KEGGprofile: An annotation and visualization package for multi-types and multi-groups expression data in KEGG pathway

Description

The function will transfer a numeric matrix into a matrix of colors, in which the colors represent the values of numeric matrix

Usage

col_by_value(x, col, range = NA, breaks = NA, showColorBar = T)

Arguments

x	a numeric matrix
col	colors used to represent the values. (See also 'Details')
range	values out of the range will be modified to in the range.
breaks	a numeric vector of three or more cut points giving the number of intervals into which x is to be cut. See also 'Details'
showColorBar	Logical. Indicates display the colorbar or not. The default value is TURE.

Details

A colorbar would also be ploted. The returned colors of the function can be used in function plot_profile. if breaks not equal to NA, col must have the same length with breaks-1.

Value

a matrix equal to x, but the values were instead by colors.

Examples

data(pho_sites_count)
col<-col_by_value(pho_sites_count,col=colorRampPalette(c('white','khaki2'))(4),
breaks=c(0,1,4,10,Inf))

Example output

KEGG.db contains mappings based on older data because the original
  resource was removed from the the public domain before the most
  recent update was produced. This package should now be considered
  deprecated and future versions of Bioconductor may not have it
  available.  Users who want more current data are encouraged to look
  at the KEGGREST or reactome.db packages
