Hi freind, My data seems to be like , and data frame name is comb.data sequence weight rsat. zFEl 1 CTTTTCTTGTT 4.6 0.00058 -7.452 3.237 2 ACTTTGAGGTG 4.1 0.00077 -7.169 3.114 3 GTCTTGAACTC 4.8 0.00055 -7.506 3.260 4 GCTTTGAAGAA 6.6 0.00019 -8.568 3.721 5 GCTTTCAACAT 7.0 0.00014 -8.874 3.854 6 TCCTTGTTCAT 3.5 0.00099 -6.918 3.004 So I need to use aggregate function based on sequence column(by=list(comb.data$sequence) for zFE column and I should need to store those results in lists..so result would be like [[1]] CTTTTCTTGTT 2.3758 3.237 [[2]] ACTTTGAGGTG 1.78977 -5.11768684 [[3]] GTCTTGAACTC 1.987455 1.260 [[1]] GCTTTGAAGAA 1.019 0.72541 [[4]] GCTTTCAACAT 0.0423 3.865754 ...so I made a code like this,,but i am facing some bugs as i mentioned before,,could you please help to solve this one??I hope now you understand my query...
the code is "data <- lapply(comb.data$zFE, function(x) aggregate(x,by=list(comb.data[["sequence"]]), quantile, probs=c(0.5,0.8,0.9), na.rm=T)) " Thanks,, -- View this message in context: http://r.789695.n4.nabble.com/How-can-I-make-a-list-using-aggregate-function-tp4634714p4634764.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
