[R] Subsetting a square marix

[Tawanda Tarakini]

I have a global matrix (e.g. table below) of species feeding. I am trying
to create specific matrix for specific sites. If for example a subset is to
have sp1, sp3 and spp only these 3 species should be appearing in the
subset (both column and rows).

I have been checking online help but I seem not to get my scenario



Sp1

Sp2

Sp3

Sp4

Sp5

Sp6
