selectVar.mcia: Selecting variables from result of MCIA

Description

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

Usage

"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

Value

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

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.
