NewStats_2samples | R Documentation |
It plots the two samples and the difference between them with their confidence intervals (CI), based on the two samples being independent or dependent.
NewStats_2samples( x, y, dep = FALSE, conf.level = 0.95, col.x = "blue", col.y = "green3", col.diff = "red", ylab.diff = "Difference" )
x |
Sample 1 |
y |
Sample 2 |
dep |
Logical indicating if the samples are dependent (Default is F) |
conf.level |
Confidence level for the interval (Default is 0.95) |
col.x |
Color to use for sample 1 |
col.y |
Color to use for sample 2 |
col.diff |
Color to use for the difference |
ylab.diff |
Label for the secondary y-axis for the difference |
The labels of the plot are generic but they can be customised using the labs()
and scale_x_discrete(labels = c())
functions. For the dependent samples case the two means are joined by a line, to indicate the dependency
