Using a string as a variable name - revisited
...'s say this returns foo as "Aulacoseira_islandica". I have another
matrix "counts" with column headers corresponding to the taxon list.
But, when I try to access the data in the Aulacoseira_islandica
column, it instead uses the data from another column. For instance...
> columndata <- counts[[foo]]
...returns the data from the wrong column. What it seems to be doing
is converting the text "Aulacoseira_islandica" to a number (25, for
some reason) and reading the count data from column number 25, instead

So some code:
myData = read.delim(myDataFile, row.names=1,header=TRUE,skip=10); #works

myColumn = myData[[question]]; #works fine, selects correct question
column data
myColumn data is now e.g.:
1

2
