Documentation for OmicsProfiles.
OmicsProfiles.AnnotatedProfile
— TypeAnnotatedProfile(omics, obs, obsindex)
AnnotatedProfile(op, omicsname, obs, obsindex)
Arguments
omics::Dict{Symbol,OmicsProfile}
: A collection of omics profile with their names in keys.op::OmicsProfile
: Single omics profile.omicsname::Symbol
: The name of givenOmicsProfile
.obs::DataFrame
: The dataframe contains meta information for observations.obsindex::Symbol
: The index of dataframeobs
.
OmicsProfiles.OmicsProfile
— TypeOmicsProfile(countmat, var, varindex; T=float(eltype(countmat)))
Arguments
countmat
: The count matrix for given omics and it will be set to key:count
.var::DataFrame
: The dataframe contains meta information for features or variables.varindex::Symbol
: The index of dataframevar
.T
: Element type ofcountmat
.
Examples
julia> r, c = (100, 500)
(100, 500)
julia> data = rand(0:100, r, c);
julia> var = DataFrame(index=1:r, C=rand(r), D=rand(r));
julia> prof = OmicsProfile(data, var, :index)
OmicsProfile (nvar = 100):
var: index, C, D
layers: count
Base.filter
— Methodfilter(col => func, p)
Returns a copy of profile p
containing data from p
for which func
returns true
.
Arguments
col
: Column name to filter.func
: A predicate function which returnstrue
/false
.p::AbstractProfile
: A profile to filter on.
Examples
julia> ngenes, ncells = (100, 500)
(100, 500)
julia> X = rand(0:10, ngenes, ncells);
julia> var = DataFrame(genesymbol=1:ngenes, A=rand(ngenes));
julia> prof = OmicsProfile(X, var, :genesymbol)
OmicsProfile (nvar = 100):
var: genesymbol, A
layers: count
julia> prof.varm[:a] = rand(ngenes, 50);
julia> prof2 = filter(:A => x -> x > 0.5, prof)
OmicsProfile (nvar = 46):
var: genesymbol, A
varm: a
layers: count
julia> obs = DataFrame(barcode=1:ncells, B=rand(ncells));
julia> ap = AnnotatedProfile(prof, :RNA, obs, :barcode)
AnnotatedProfile (nobs = 500):
obs: barcode, B
RNA => OmicsProfile (nvar = 100):
var: genesymbol, A
varm: a
layers: count
julia> ap2 = filter(:B => x -> x > 0.5, ap)
