ESplot {gap}R Documentation

Effect-size plot

Description

The function accepts parameter estimates and their standard errors for a range of models.

Usage

ESplot(ESdat,SE=TRUE,logscale=TRUE,alpha=0.05,xlim=c(-2,8),v=1,...)

Arguments

ESdat A data frame consisting of model id, parameter estimates and standard errors or confidence limits
SE If TRUE, the third column of ESdata contains the standard error estimates
logscale If TRUE, indicates log-scale as appropriate for odds ratio
alpha Type-I error rate used to construct 100(1-alpha) confidence interval
xlim Lower and upper limits of the horizontal axis, roughly corresponding to confidence limits
... Other options for plot
v Location of the vertical line
