Check str(your_matrix)

[adnan.sabar7865]

chr [1:17, 1:13] "0.15807803" "0" "0.073840408" "0.001968405" "0.000403775" ...

attr(*, "dimnames")=List of 2 ..$ : chr [1:17] "p__Bacteroidetes;c__Bacteroidia" "p__Bacteroidetes;c__Cytophagia" "p__Bacteroidetes;c__Flavobacteriia" "p__Bacteroidetes;c__Sphingobacteriia" ... ..$ : chr [1:13] "kisshion.influent" "Toba.influent" "kisshion.effluent" "Toba.effluent" ... Thats answer

Then you have your answer, all the content is of class "character" you must convert your data to matrix/numeric

[adnan.sabar7865]

I didn't understand how i can convert

[Basti]

as.matrix(df)

or

  apply(df, 2 ,as.numeric)

etc... depending on your data

[adnan.sabar7865]

chr [1:17, 1:13] "0.15807803" "0" "0.073840408" "0.001968405" "0.000403775" ...

• attr(*, "dimnames")=List of 2 ..$ : chr [1:17] "p__Bacteroidetes;c__Bacteroidia" "p__Bacteroidetes;c__Cytophagia" "p__Bacteroidetes;c__Flavobacteriia" "p__Bacteroidetes;c__Sphingobacteriia" ... ..$ : chr [1:13] "kisshion.influent" "Toba.influent" "kisshion.effluent" "Toba.effluent" ...

Thats answer
