Re: [R] Merging multiple .csv files into one dataframe
I really think you need to create a simple reprex to show us what you want to do. In doing so, you may figure out how to get what you want. I suspect you may also need to spend some more time learning R -- following rote examples can be a fool's errand if you don't know the basics.

[R] Merging multiple .csv files into one dataframe
Hi, I am trying to merge columns from four different .csv files into one dataframe. I am trying to do something like this https://statisticsglobe.com/merge-csv-files-in-r . I am taking long format .csv files, 1 being the base file (testing-long.csv) which I change to wide format first and the three others being supplemental files that should add columns plight, plightLitter, Root Biomass, NO3Soil, NH4Soil and then add data to cells where the it matches any one of the values for columns, "Exp", "Year", "Field", "Plot", "NTrt", "NAdd", "NitrAdd", "NAtm.NAdd". So the values for the supplemental files need not match every single one of the columns listed above and if the value does not match all the columns exactly the cell for that column/row should not be filled. When I try the method from that website, I do not see the supplemental columns being added. I am wondering if there is a better way to merge multiple .csv files. I hope this makes sense, but it is quite confusing even to me, so I am more than happy to clarify. I am attaching the files in question. __ 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.
