I'm trying to use ComBat function in sva package. So, I followed example inhttp://jtleek.com/genstats/inst/doc/02_13_batch-effects.html 

However,

Error in ComBat(dat = edata, batch = batch, mod = modcombat, par.prior = TRUE, : unused arguments (dat = edata, batch = batch, mod = modcombat)

was occurred. How can I fix it?

Thanks in advance
