sm_forest_annot: Annotation of the error range on the forest plot

Description

Annotation of the error range on the forest plot

Usage

sm_forest_annot(
  data,
  x,
  y,
  errorbar_type = "ci",
  text.params = list(size = 4, color = "black"),
  sep_level = 2,
  ...
)

Value

Annotations showing the range of uncertainty will printed on the forest plot.

Arguments

data

Data frame variable that is used for plotting.

x

Column of the data frame that represents the x-axis.

y

Column of the data frame that represents the y-axis.

errorbar_type

This argument determines the errorbar type. If it is set to 'se', standard error bar will be shown. If it is set to 'sd' (default), the error bar will display standard deviation. If it is set to 'ci', the error bar will display 95% confidence interval.

text.params

List of parameters for the text annotation, such as color, size etc

sep_level

A numerical value that controls the level of the separation between the text annotation and the average point. If it's 0, all of these are clustered together. If it's higher (and more positive), the text annotations will increasingly go above the mean point. Default is set to 2. The values can be negative so that the texts can be below the mean point. There is no limit of the range for this argument. Ideally, this should equal to the sep_level in sm_forest().

...

Parameters for the text annotation, such as size and color etc.

Examples

library(ggplot2)
library(smplot2)

day1 = rnorm(20,0,1)
day2 = rnorm(20,5,1)
day3 = rnorm(20,6,1.5)
day4 = rnorm(20,7,2)
Subject <- rep(paste0('S',seq(1:20)), 4)
Data <- data.frame(Value = matrix(c(day1,day2,day3,day4),ncol=1))
Day <- rep(c('Day 1', 'Day 2', 'Day 3', 'Day 4'), each = length(day1))
df2 <- cbind(Subject, Data, Day)

 scale_color_manual(values = sm_palette(4)) +
 sm_forest_annot(data = df2, x = Value, y = Day, sep_level = 3)
