selectVar.mcia: Selecting variables from result of MCIA

In mengchen18/omicade4: Multiple co-inertia analysis of omics datasets

Description

The selection of variables based on co-ordinates of MCIA variable space. The function is called by selectVar

Usage

## S3 method for class 'mcia'
selectVar(x, axis1 = 1, axis2 = 2, 
  a1.lim = c(-Inf, Inf), a2.lim = c(-Inf, Inf), 
  sepID.data = NULL, sepID.sep = "_", ...)

Arguments

x	An object of class mcia, the result returned by mcia.
axis1	Integer, the column number for the x-axis. The default is 1.
axis2	Integer, the column number for the y-axis. The default is 2.
a1.lim	The limited range of x-axis of selected. It could be either a vector (containing 2 numbers, the first value limiting the lower boundary, the second value limiting the upper boundary) or a list of vectors, each of which contains two number. If it is a list, the length of the list should be the same with number of data.frames in mcia.
a2.lim	The limited range of y-axis.
sepID.data	See plotVar.mcia
sepID.sep	See plotVar.mcia
...	Other arguments

Details

mcia projecting variables (genes) from different datasets to a lower dimensional space. This function supplies a method selecting variables according to the co-ordinates of variables.

Value

Returns a data.frame describing which variables are presented on which data.frames within the limited region(s).
