I have a list of data as follows. > list(data.frame(name="sample1", red=20), data.frame(name="sample1", > green=15), data.frame(name="sample2", red=10), data.frame(name="sample 2", > green=30)) [[1]] name red 1 sample1 20
[[2]] name green 1 sample1 15 [[3]] name red 1 sample2 10 [[4]] name green 1 sample2 30 I would like to massage this into a data frame like this: name red green 1 sample1 20 15 2 sample2 10 30 I'm imagining I can use aggregate(mylist, by=samplenames, merge) right? But how do I get the list of samplenames? How do I subset each dataframe inside the list? ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
