Dear R Users, I have created a 1500 x 20000 data frame - DataSeq. Each of the 1500 rows represents a data sequence. I have another data frame iData that stores the information of these 1500 data sequences in the same order, for example, condition, gender, etc.
If I use "subset" to select certain groups within iData according to some criteria that I have set, e.g. condition, gender Then how can I used the retrieved subset of iData to point to and retrieve corresponding rows in the DataSeq data.frame for manipulations and analysis? I hope some of you can give me some idea! Thank you very much!!! - John ______________________________________________ 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.
