I am relatively new to R and am trying to do some basic data manipulation. Basically I have a table (csv - table 1) of data for a set of samples (rows), and a second table (table 2) of information about a subset of samples of particular interest. I want to pull out the data from table 1 for the samples in table 2, either by: * Merging the two tables based on a common identifier (SampleID - may have a different header in the two tables), and filter for overlapping entries (preferred approach) * OR filter table 1 for entries where SampleID matches to one in a list taken from table 2
Any help would be gratefully recieved. -------------------------------------------------------------------------- AstraZeneca UK Limited is a company incorporated in Engl...{{dropped:21}} ______________________________________________ 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.
