plotLine: Line plot

In bgovaerts/LMWiRe: Linear Models for Wide Responses

Line plot

Description

Generates the response profile of one or more observation i.e. plots of one or more rows of the outcomes matrix on the y-axis against the m response variables on the x-axis. Depending on the response type (spectra, gene expression...), point, line or segment plots are offered.

Usage

plotLine(
  Y,
  rows = 1,
  type = c("l", "p", "s"),
  title = "Line plot",
  xlab = NULL,
  ylab = NULL,
  xaxis_type = c("numeric", "character"),
  stacked = FALSE,
  ncol = 1,
  nrow = NULL,
  facet_label = NULL,
  hline = 0,
  size = 0.5,
  color = NULL,
  shape = 1,
  theme = theme_bw()
)

Arguments

Y	A numerical matrix containing the rows to be drawn.
rows	A vector with either the row name(s) of the Y matrix to plot (character) or the row index position(s).
type	Type of graph to be drawn: "p" for point, "l" for line or "s" for segment.
title	Plot title.
xlab	If not NULL, label for the x-axis.
ylab	If not NULL, label for the y-axis.
xaxis_type	The data type of the x axis: either "numeric" or "character".
stacked	Logical. If TRUE, will draw stacked plots, otherwise will draw separate plots.
ncol	If stacked is FALSE, the number of columns to represent the separate plots.
nrow	If stacked is FALSE, the number of rows to represent the separate plots.
facet_label	If stacked is FALSE, the labels of the separate plots.
hline	If not NULL, draws (a) horizontal line(s).
size	Argument of length 1 giving the points size (if type == "p") or the line size (if type == "l" or "s").
color	If not NULL, argument of length 1 with possible values: "rows", a color name (character) or a numeric value representing a color.
shape	The points shape if type == "p" (argument of length 1).
theme	ggplot theme, see ?ggtheme for more info.

Value

A line plot (ggplot).

Examples

plotLine(Y = UCH$outcomes)

# separate plots
plotLine(Y = UCH$outcomes, rows = c(1:4), hline = NULL)
plotLine(Y = UCH$outcomes, rows = c(1:4), color = 2)
plotLine(Y = UCH$outcomes, rows = c(1:8), ncol=2)
plotLine(Y = UCH$outcomes, type = "p",
         rows = c(1:8), ncol=2)

# stacked plots
library(ggplot2)
plotLine(Y = UCH$outcomes, rows = c(1:4),
         stacked = TRUE, color = "rows") +
         scale_color_brewer(palette="Set1")
