Cleaning Up Timestamps in R: How to Add a Minute Between Start and End Dates
Here is the corrected code for cleaning up timestamps by adding a minute between start and end: library(tidyverse) df %>% mutate(start = as.POSIXct(ifelse(!is.na(lead(start)) & lead(start) < end, lead(start) - 60, start), origin = "1970-01-01 00:00:00")) %>% mutate(end = as.POSIXct(ifelse(!is.na(lead(start)) & lead(start) < end, lead(start) + 60, end), origin = "1970-01-01 00:00:00")) This code adds a minute between start and end for each row. The rest of the steps remain the same as before.
