[R] Loess CI

I am trying to (semi) calculate the confidence intervals for a loess smoother (function: loess()), but have been thus far unsuccessful. The CI for the loess predicted values, yhat, are apparently yhat +- t*s * sqrt(w^2), where s is the residual sum of squares and w is the weight function Corre

[R] Lattice help: Dotplot

With Dotplot, I'm trying to make a figure that will ultimately have the same x-axis (which will be my response variable and the error bars), but the y-axis will consist of a different label for every point. Here's my code: Dotplot(fTaxonGrouped ~ Cbind(normSlope,normLwr,normUpr)|fGroup, groups=fEp
