Warning in doTryCatch(return(expr), name, parentenv, handler) :

Warning: The vignette title specified in \VignetteIndexEntry{} is different from the title in the YAML metadata. The former is "ROCR", and the latter is "ROCR: visualizing classifier performance in R". If that is intentional, you may set options(rmarkdown.html_vignette.check_title = FALSE) to suppress this check.
