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.
