Would like to add this to example for plotmath. Can you help?

### Take sequence parallel to values of myx inside critical region
specialY <- myDensity[myx < criticalValue]
# Polygon makes a nice shaded illustration
polygon(c(specialX[1], specialX, specialX[length(specialX )]), c(0,
specialY, 0), density=c(-110),col="lightgray" )
shadedArea <- round(pnorm(mu - 1.96 * sigma, mean=mu, sd=sigma),4)
### I want to insert annotation about area on left side.

al3 <- bquote(phantom(0) == .(round(shadedArea,3)))
