Is this supposed to represent your data?

> Call ERBB2|2064 ERBB2_Status ERBB2-MUT
> A 7.214E-01 CHANGE MUT
> B -4.208E-02 NEUTRAL MUT
> D 1.080E+00 NEUTRAL MUT
> C 2.347E-01 NEUTRAL MUT
> ggplot(data=testdata, aes(x=Call, y=ERBB2.2064)) +
> geom_boxplot(aes(fill=ERBB2_Status),width=0.8)+theme_bw()+geom_point(data=subset(testdata,ERBB2.MUT=="MUT"),aes(shape=Call,color="Red"))
