To adjust the code to match your requirements, you can use mutate with a conditional statement that checks if there’s an action == 'Return' within each group and uses the difference between these two times. Here is how you could do it: library(dplyr) df %>% mutate( timediffsecs = if (any(action == 'Return')) dt[action == 'Return'] - dt[action == 'Release'] else Sys.time() - as.POSIXct(dt), action = replace(action, n() > 1 & action == "Release", NA) ) This will calculate the difference between dt and Sys.

Understanding the External Accessory Framework and Connection Hiccups The External Accessory Framework (EAF) is a part of Apple’s iOS SDK, which allows developers to interact with external accessories connected to an iPhone or iPad.
