...(plnorm(x_lcl, mean, var) - (alpha/2))^2 b <- (plnorm(x_ucl, mean, var) - (1-alpha/2))^2 return(a+b) } optimize(fn=prior, interval = c(-5, 100), 1, 20) I understand that this problem has a closed form solution, but I would like to make this a general function.

Can I add a line break to the paste() function to return the following: 'this is the first line' 'this is the second line' instead of 'this is the first line this is the second line' ?

Hello, I am interested in finding the quantile of the mean of a vector, something analogous to using the pnorm(), but for an mcmc chain instead of a distribution with known parameters. One approach would be to write a function that finds the index of x_i that minimizes (x-mean(x))^2 I suspect there is a function available to do this, but I can't find it? Thank you, David

Hello Prof. Harrell and dear R-help mailing list, I wish to perform a non-parametric repeated measures anova. If what I read online is true, this could be achieved using a mixed Ordinal Regression model (a.k.a: Proportional Odds Model). I found two packages that seems relevant, but couldn't find any vignette on the subject: http://cran.r-project.org/web/packages/repolr/
