Dear all, I faced with the problem using bear 2.8.3 (R 3.4.1, x64) when I run NCA. After importing a csv file at the end I received a message about some data errors. In the data_err_log.txt file it looks like this: *** The error occurs in 'time'. subj seq prd time conc 1 2 1 0,00 0,000 1 2 1 0,17 NA 1 2 1 0,33 NA 1 2 1 0,50 0,098 1 2 1 0,67 0,150 1 2 1 0,83 0,252 1 2 1 1,00 0,337 I've checked all data fields manually and no errors have been detected. Surprisingly, when I use bear 2.7.7 and the same csv file no errors detected and the bear do his job. Does anybody know how to exactly detect the particular "errors in time" and resolve this issue in bear 2.8.3? Regards, Roman |

Dear roman_max, Wait. I will check the codes again. Your data looks OK for me. If you need to run analysis immediately, please replace the comma (,) with the period (.) for the decimal. It then should be OK (I have confirmed this). Sorry about my previous messages. ❝ *** The error occurs in 'time'. ❝ ❝ subj seq prd time conc ❝ 1 2 1 0,00 0,000 ❝ 1 2 1 0,17 NA ❝ 1 2 1 0,33 NA ❝ 1 2 1 0,50 0,098 ❝ 1 2 1 0,67 0,150 ❝ 1 2 1 0,83 0,252 ❝ 1 2 1 1,00 0,337 — All the best, -- Yung-jin Lee bear v2.9.2:- created by Hsin-ya Lee & Yung-jin Lee Kaohsiung, Taiwan https://www.pkpd168.com/bear Download link (updated) -> here |

Dear yjlee168, Thanks for the propmpt reply and the tip concerning separators. But I had to change systemic defaults (from comma to dot) because traditionally in Russia the decimal separator is comma. Now everythig is fine with the data and analysis as well. Regards, Roman |

Dear roman_max, Sorry about this error. I did not notice that the function fread() from package data.table is no longer working as smartly as previously. It cannot automatically identify the decimal separator correctly. It used to be able to do that. The decimal point should be either comma or period. However identification of the column separator still works fine with fread(). It sounds like that I need add an extra option for this in GUI (hopefully not), like the old version. But I will keep searching for solution for this. The error affects all dataset using comma as decimal separator. Thank you so much for bringing up this error here. — All the best, -- Yung-jin Lee bear v2.9.2:- created by Hsin-ya Lee & Yung-jin Lee Kaohsiung, Taiwan https://www.pkpd168.com/bear Download link (updated) -> here |
