Hi, I have a small problem with the function split() and would appreciate your help.
I have a table called “XXX” with 2 columns and 49 rows. The 49 rows belong to 8 different levels (electrode1, ...,electrode8). I want to split the table always at the row where “electrode1” starts again so that I can export 7 individual dataframes (numbered “dataframe1” to ”dataframe7”) which contain always electrode1 as first level (always three rows) with the varying number of rows for electrodes2-8 below. I tried the split function with various setups: t <- as.factor(XXX$electrode) dataframeX <- split(XXX, f=(levels=t)) But this doesn’t work. Could you please help. Thank you! Dennis This is the table "XXX" electrode length electrode1 5.7 electrode1 6.3 electrode1 6.2 electrode2 11.4 electrode2 9.7 electrode1 5.7 electrode1 6.3 electrode1 6.2 electrode3 14.2 electrode3 14.8 electrode3 12.6 electrode1 5.7 electrode1 6.3 electrode1 6.2 electrode4 17.0 electrode4 16.3 electrode4 17.8 electrode4 18.3 electrode4 16.9 electrode4 18.5 electrode1 .... .... .... electrode5 .... .... .... electrode1 .... electrode6 .... electrode1 .... electrode7 .... electrode1 .... electrode8 .... ______________________________________________ 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.
