Assuming your data is in a data.frame called df, try this:

attach(df)
TR.groups <- cut(TvarRatio, seq(0.07, 0.11, 0.01))
m <- table(Mutation_Status, TR.groups)
mut.no <- dim(m)[1]
barplot(m, col=seq(mut.no), xlab="TvarRatio", ylab="Frequency")
legend("topleft", dimnames(m)[[1]], fill=seq(mut.no), 
title="Mutation_Status")
