If you are looking for docstrings:
On Julia 0.3:
julia> help(qr)
INFO: Loading help data...
Base.qr(A, [pivot=false,][thin=true]) -> Q, R, [p]
Compute the (pivoted) QR factorization of "A" such that either
"A = Q*R" or "A[:,p] = Q*R". Also see "qrfact". The default
is to compute a thin factorization. Note that "R" is not extended
with zeros when the full "Q" is requested.
On Julia 0.4:
!julia> @doc qr
qr(A [,pivot=Val{false}][;thin=true]) -> Q, R, [p]
Compute the (pivoted) QR factorization of A such that either A = Q*R or
A[:,p] = Q*R. Also see qrfact. The default is to compute a thin
factorization. Note that R is not extended with zeros when the full Q is
requested.
