You did not offer the input statements that you used. The warning suggest to me that you are using a function for reading SPSS or SAS data files.. The "here it is not.png" image shows a factor variable, suggesting there was a non-numeric value detected in the automatic guessing process used by the read.* functions, and that a character/integer representation was automatically chosen for only one. The otehr two were all unquoted integers and so came in as integers. > > for two datasets out of three. > > > Looking at the tables, you see that the variable grows normally...

And if we are to advise on how to fix a dataset, then we would need to know what you consider correct, which you have not yet stated. > > > Thank you very much for your time. > <here it is missing.png><here it is > not.png>______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
