Testing it now. Will provide more details soon.

I cannot reproduce the issue in version 3,15 with mariadb and php71

Didn't have time to check all the questions. As far as I remember, I had this Unknown type error when timings was enabled (survey format question by question) + some questions (e.g., text display) were included in the survey.

I've just tried it again with the latest version 3.15.8 and mysql 5.0.12 and the issue persists (see attached screenshot of the .R syntax file that is produced)

@cdorin (https://bugs.limesurvey.org/view.php?id=13942#c50466) I have timings enabled and a wide variety of questions (multiple choice, ranking, free text, etc)

thank you @icecliber81 for your confirmation. Did some tests. The "Unknown type" error appears when save timings is enabled. The timings can be imported in R in LimeSurvey 2.73. But not LS 3.15.8. . In LS 3.15, the data gets exported in the data file, but the syntax file cannot read the timings since there is no command for such a thing (hence, the error type). I have also attached my .lsa files for LS 2.73 and LS 3.15.

Extra: saw that "seed" is now being imported in LS 3.15.8 while seed was not imported in 2.73 (see screenshot)

@cdorin, so will there be a solution in LS (like automatically disabling timing export when exporting to R) or is the only way around this disabling timings in the LS survey?

@iceclimber81, we are working on a fix now since we already have a couple of users who have already reported this issue. Unfortunately, I cannot provide any ETA. You can wait for the solution or try a different workaround. Please note that even if you disable the timings, they are already stored in the response table. Therefore, the error will still be shown. A customized script is needed to import your .csv file from LimeSurvey into R.

My comment is more like a warning sign for those that export their data to R and use Save timings. We hope to solve this asap.

@f_funke, this is the R bug we were talking about.
