Hi
I have a script which is designed to gather data from individual columns
from a file, which is an output from an instrument. the file has multiple
sections and each a section has data under each column (vars), I am using
the name of the column as a variable to gather the column ID using
vidx<-grep(vars[vi],gsub("[[:punct:]]","",strrl1[[datbeg-1]]),ignore.case=T)
the vidx stores the column ID for each 'vars', which in subsequent step
is
stored in a temp vector for analysis
strrl1[[datbeg-1]] is the position in the file where the data begins( the
data is given below)
This is working fine when i have all the unique names for 'vars' the
trouble
started when I started working with files having column names starting with
exactly same alphabets for eg, Apo AII and Apo AI the vidx returns multiple
column ids and in the following example it 'vidx' returns 3 and 5
