You could do this:
        con <- rawdata$V1
        total <- rawdata$V2

Or you could add in a col.names= argument to the read.table() function,

rawdata <- read.table(file='data.txt', sep='\t', header=FALSE, 
col.names=c("con", "total")) 
then refer to each vector in the data.frame as

rawdata$con

and 

rawdata$total
