makeProfileMatrix(profiles, type = c("ramclust", "graphviz"),
  addIndex = ifelse(type[[1]] == "ramclust", TRUE, FALSE),
  reindexProfiles = 0)

`profiles`	A profiles object from enviMass
`type`	`ramclust` or `graphviz`, in the latter case the retention time is inserted as a first row (not only in the column names).
`addIndex`	If `TRUE`, add a sample index column in front of the table, as required by RAMClust.

A matrix m x n, where the rows (sic) are the samples and the columns are the profiles (features) without "profile 0". The columns are named profileID_RT. This is a requirement for ramclustR (which usually uses mz_RT, but actually doesn't use mz for calculation and therefore the content is arbitrary. It's easier to use the profile ID for precise lookup.)
