Hello R Community, I inadvertently updated packages via R Studio when a package was open. Now when R Studio is opened the message below appears in the console panel. Error in loadNamespace(name) : there is no package called ‘yaml’ Error in loadNamespace(name) : there is no package called ‘yaml’

[R] Bayes Factor

Hello R Community; Just posted a question about Bayes Factor. But, just answered my own question. What is needed is to convert a 'dplyr' data frame into a standard data frame. competition2 <- data.frame(competition), where 'competition' is a 'dplyr' data frame with the following class structure.

[R] confidence intervals for orthogonal contrasts

Hi R users, Is there a way to calculate a confidence interval for each contrast in a set of orthogonal contrasts? The ‘multcomp’ package will calculate a CIs at the 95% family-wise confidence level. But, these confidence intervals are extremely wide. Thanks for your help. Best regards, James ___
