[BioC] error on loading ratioConvert() in minfi

[guest [guest]]

Dear Users,

I tried to convert the set to ratioset using ratioConvert(), but it has an error message

> ratioConvert(RGset, what = c("beta", "M", "both"), keepCN = TRUE)
Error: could not find function "ratioConvert"

I installed minfi and load the library, I don't get it why this error message coming out?

Thanks,
