plotCV: Plot CV values

In tnaake/MatrixQCvis: Shiny-based interactive data-quality exploration for omics data

Plot CV values

Description

The function plotCV displays the coefficient of variation values of set of values supplied in a data.frame object. The function will create a plot using the ggplot2 package and will print the values in the different columns in different colors.

Usage

plotCV(df)

Arguments

df	data.frame containing one or multiple columns containing the coefficients of variation

Details

Internal usage in shinyQC.

Value

gg object from ggplot2

Examples

x1 <- matrix(seq_len(10), ncol = 2)
x2 <- matrix(seq(11, 20), ncol = 2)
x3 <- matrix(seq(21, 30), ncol = 2)
x4 <- matrix(seq(31, 40), ncol = 2)

## calculate cv values
cv1 <- cv(x1, "x1")
cv2 <- cv(x2, "x2")
cv3 <- cv(x3, "x3")
cv4 <- cv(x4, "x4")

df <- data.frame(cv1, cv2, cv3, cv4)
plotCV(df)
