Comparing 2 dale columns
Dear R fellows, I created a new column Date_flag to compare the dates of COL1 and COL2 using the code below. But it showed that 5/1/15 is greater than 6/1/2014 and 5/1/2015 greater than 7/1/2014 despite the year is greater. How do I fix that? I did try to format as %y/%m/%d but it does not fix that. data$Date_Flag <- ifelse(data$COL2 > data$COL1, 0,1) COL1 COL2 6/1/14

[LLVMdev] Removing legacy profiling code from LLVM
It appears to me as if you're proposing removing all the existing readers/writers, both the really old ones and the metadata ones, the instrumentation passes, and the implied file format for profile data. Is this correct? While I'm not against considering migrating our work, I think it would be better if the new system was in place before removing the old. --Mike

Please help(urgent) - How to simulate transactional data for reliability/survival analysis
In principle what you need to do is the following: - break down the time you wish to simulate into intervals. - for each interval, and each failure mode, determine the probability of an event. Determining the probability is the fun part, where you make your domain knowledge explicit and include all the factors into your model: cumulative load, failure history, pressure, temperature,

Please help(urgent) - How to simulate transactional data for reliability/survival analysis
Thanks Boris and Bret, I was successful in simulating granular/transactional data. Now I need some guidance to transform the same data in format acceptable for survival analysis i.e below format: pump_id | event_episode_no. | event(0/1) | start | stop | time_to_dropout The challenge I'm experience is to generate the 'start' and 'stop' in units of minutes/days from single
