In NMikolajewicz/scMiko: scRNAseq analysis functions. Developed using Seurat framework.

Convert values to color gradient

Description

Converts ranges of values to corresponding color along color gradient, specified by 3 colors (low color, middle color and high color)

Usage

value2col(
  values,
  limit = NULL,
  gradient.length = 100,
  low.col = "skyblue",
  mid.col = "grey",
  high.col = "tomato"
)

Arguments

limit	numeric specifying limit of color range. If unspecified, limit <- max(c(abs(min(Values)), abs(max(Values))))
gradient.length	Numeric specifying number of bins to split gradient into. Default is 100.
low.col	Color representing low values. Default is "skyblue"
mid.col	Color representing mid values. Default is "grey"
high.col	Color representing high values. Default is "tomato"
Values	vector of numerical values to convert to colors

Value

vector of colors.
