Package: rtprep Title: Screening, Trimming, and Aggregating Response Time Data Version: 0.1.0.9000 Authors@R: person("Gidon T.", "Frischkorn", , "gfrischkorn@icloud.com", role = c("aut", "cre", "cph"), comment = c(ORCID = "0000-0002-5055-9764")) Description: A uniform interface to common response time preprocessing decisions that precede analysing aggregated response times or fitting an evidence accumulation model. Screening rules from different preprocessing routines -- absolute cutoffs, standard deviation and median absolute deviation criteria, recursive moving criteria, and model-based mixture flagging -- all return the same per-trial object, so that consequences of a preprocessing choice can be compared rather than assumed. The package also provides aggregation into EZ-diffusion summary statistics, diagnostics reporting what each rule removed and where rules disagree. Finally, generators for response time data with contaminants of known type are provided, so that a chosen pipeline can be tested against ground truth. Screening criteria follow Van Selst and Jolicoeur (1994) , the contaminant mixture Ratcliff and Tuerlinckx (2002) , and the EZ-diffusion equations Wagenmakers, van der Maas and Grasman (2007) .
