plot: Plots

In PowerUpR: Power Analysis Tools for Multilevel Randomized Experiments

Description

Plots statistical power, minimum detectable effect size (MDES), or MDES difference (MDESD) curves with (1-α)x100 % confidence interval.

Usage

  ## S3 method for class 'power'
plot(x, ypar = "power",  xpar = NULL,
          xlim = NULL, ylim = NULL,
          xlab = NULL, ylab = NULL,
          main = NULL, sub = NULL,
          locate = FALSE, ...)

  ## S3 method for class 'mdes'
plot(x, ypar = "power",  xpar = NULL,
          xlim = NULL, ylim = NULL,
          xlab = NULL, ylab = NULL,
          main = NULL, sub = NULL,
          locate = FALSE, ...)

  ## S3 method for class 'mrss'
plot(x, ypar = "power",  xpar = NULL,
          xlim = NULL, ylim = NULL,
          xlab = NULL, ylab = NULL,
          main = NULL, sub = NULL,
          locate = FALSE, ...)

Arguments

x	an object returned from one of the PowerUpR functions.
ypar	character; "mdes" or "power" on y axis .
xpar	character; one of the sample sizes on x axis.
xlim	limits for xpar.
ylim	limits for ypar.
xlab	x axis label (ignored for objects returned from power.med211(), power.med221(), and power.med321() functions).
ylab	y axis label (ignored for objects returned from power.med211(), power.med221(), and power.med321() functions).
main	title for the plot (ignored for objects returned from power.med221() and power.med211() functions).
sub	subtitle for the plot (ignored for objects returned from power.med221() and power.med211() functions).
locate	logical; TRUE locates parameter values for design x on the plot.
...	other graphical parameters to pass to plot.new().

Examples

design1 <- mdes.cra3(rho3=.06, rho2=.17, n=15, J=3, K=60)
plot(design1, ypar = "mdes", xpar = "K", xlim = c(30, 100))
plot(design1, ypar = "power", xpar = "K", xlim = c(30, 100))

design2 <- power.cra3(es=.269, rho3=.06, rho2=.17, n=15, J=3, K=60)
plot(design2, ypar = "mdes", xpar = "K", xlim = c(30, 100))
plot(design2, ypar = "power", xpar = "K", xlim = c(30, 100))
