Question

Is there a way to read a simple text key-value file in R …

Key1=Value1
Key2=Value2
Key3=Value3

Ideally I want to access the data like this:

myfile$Key1 should return Value1 , myfile@Key2 should return Value2
and so on

Cheers!

P.S I looked into the stashR and the filehash packages and while these packages implement nice key value databases, they don’t store the database in simple/readable text format.

What about something like this:

dframe <- read.table(file='yourfile.txt',header=FALSE,
                     sep='=',col.names=c('Key','Value'))

then, if you want a faster access by key, you can use data.table e.g. :

library(data.table)
dframe <- read.table(file='yourfile.txt',header=FALSE,
                     sep='=',col.names=c('Key','Value'))
dtable <- data.table(dtfrm,key='Key')

dtable['Key1']
