meta.ave.plot {vcmeta} | R Documentation |
Forest plot for average effect sizes
Description
Generates a forest plot to visualize effect sizes estimates and overall averages from the meta.ave functions in vcmeta. If the column exp(Estimate) is present, this function plots the exponentiated effect size and CI found in columns exp(Estimate), exp(LL), and exp(UL). Otherwise, this function plots the effect size and CI found in the columns Estimate, LL, and UL.
Usage
meta.ave.plot(
result,
reference_line = NULL,
diamond_height = 0.2,
ggtheme = ggplot2::theme_classic()
)
Arguments
result |
|
reference_line |
Optional x-value for a reference line. Only applies if focuse is 'Difference' or 'Both'. Defaults to NULL, in which case a reference line is not drawn. |
diamond_height |
|
ggtheme |

Value
Returns a ggplot object. If stored, can be further customized via the ggplot API
Examples
# Plot results from meta.ave.mean2
m1 <- c(7.4, 6.9)
m2 <- c(6.3, 5.7)
sd1 <- c(1.72, 1.53)
sd2 <- c(2.35, 2.04)
n1 <- c(40, 60)
n2 <- c(40, 60)
result <- meta.ave.mean2(.05, m1, m2, sd1, sd2, n1, n2, bystudy = TRUE)
meta.ave.plot(result, reference_line = 0)
# Plot results from meta.ave.meanratio2
# Note that this plots the exponentiated effect size and CI
m1 <- c(53, 60, 53, 57)
m2 <- c(55, 62, 58, 61)
sd1 <- c(4.1, 4.2, 4.5, 4.0)
sd2 <- c(4.2, 4.7, 4.9, 4.8)
cor <- c(.7, .7, .8, .85)
n <- c(30, 50, 30, 70)
result <- meta.ave.meanratio.ps(.05, m1, m2, sd1, sd2, cor, n, bystudy = TRUE)
