MBplotBlocks: Customizable Plots of Blocks

Description

Plots blocks related information of MBPCA, ComDim, MBPLS or MBWCov with several options of customization.

Usage

MBplotBlocks(
  res,
  which = "explained.blocks&Y",
  axes = c(1, 2),
  blocks.axes = 1:max(axes),
  title = NULL,
  size = 2.25
)

Value

The required plot.

Arguments

res

An object resulting from MBPCA, ComDim, MBPLS or MBWCov.

which

Either "explained.blocks&Y", "scree", "structure" or "blocks.axes". See details.

axes

Which global dimensions should be plotted? Only useful if which=structure or which=blocks.axes

blocks.axes

Which individual blocks dimensions should be correlated with global ones? Only useful if which=blocks.axes

title

An optional title to be added to the plot.

size

The overall size of labels, points, etc.

Details

• explained.blocks&Y: Barplot of the percentages of inertia explained in each block of variables (and Y for MBPLS or MBWCov) by each global components.

• scree: Barplot of the saliences of each block of variables on each global components.

• structure: Blocks coordinates (saliences) on the global selected axes

• blocks.axes: Correlations of the selected individual blocks.axes with the global selected axes.

Examples

# Unsupervised example

data(ham)
X=ham$X
block=ham$block
res.mbpca <- MBPCA(X,block, name.block=names(block))
MBplotBlocks(res.mbpca,which="explained.blocks&Y")
MBplotBlocks(res.mbpca,which="scree")
MBplotBlocks(res.mbpca,which="structure")
MBplotBlocks(res.mbpca,which="blocks.axes")

# Supervised example

data(ham)
X=ham$X
block=ham$block
Y=ham$Y
res.mbpls <- MBPLS(X, Y, block, name.block=names(block))
MBplotBlocks(res.mbpls,which="explained.blocks&Y")
MBplotBlocks(res.mbpls,which="scree")
MBplotBlocks(res.mbpls,which="structure")
MBplotBlocks(res.mbpls,which="blocks.axes")
