Details

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

Examples

rs12075 <- data.frame(id=c("CCL2","CCL7","CCL8","CCL11","CCL13","CXCL6","Monocytes"),
                      b=c(0.1694,-0.0899,-0.0973,0.0749,0.189,0.0816,0.0338387),
                      se=c(0.0113,0.013,0.0116,0.0114,0.0114,0.0115,0.00713386))
ESplot(rs12075)

# The function replaces an older implementation.

       id=c("Basic model","Adjusted","Moderately adjusted","Heavily adjusted","Other"),
