mply_dbl: apply function that always returns a numeric matrix

In const-ae/proDD: Identifying Differentially Abundant Proteins from Label-Free Mass Spectrometry Data

Description

The function is modelled after 'vapply', but always returns a matrix with one row for each iteration. You need to provide the number of elements each function call produces beforehand (i.e. the number of resulting columns). For a more flexible version where you don't need to provide the number of columns see msply_dbl

Usage

mply_dbl(x, FUN, ncol = 1, ...)

msply_dbl(x, FUN, ...)

Arguments

x	a vector that will be passed to 'vapply' or a matrix that will be passed to apply with MARGIN=1.
FUN	the function that returns a vector of length ncol
ncol	the length of the vector returned by 'FUN'.
...	additional arguments to FUN

Value

a matrix of size length(x) x ncol

Functions

• mply_dbl: apply function that always returns a numeric matrix

• msply_dbl: flexible version that automatically infers the number of columns
