Hello dear R-users, today I have a question that I completely do not know how to solve (R-newbie!).
In a temperature chamber I have measured temperature over time. The result is shown in the attached eps-file (if attachments are shown): There are two temperature levels, 150°C and -40°C. A complete cycle includes about 30 minutes upper temperature, quick change to the lower level, 30 minutes hold at lower level. Then the temperature rises again to the upper level and a new cycle begins. About 500 cycles have been completed. How can I count the number of cycles that have been completed? The data does not only include perfect temperature cycles. Once in a while the machine would stand still and for a day or so the temperature would remain at room temperature. So I cannot simply divide the measured time by the duration of a cycle... Thanks a lot for your support, if necessary I could also provide the dataset. Antje <<Temperaturzyklen.eps>>
