plot3DWithProj: 3D plot of PC scores with projections on coordinate planes

In randPedPCA: Fast PCA for Large Pedigrees

3D plot of PC scores with projections on coordinate planes

Description

3D plot of PC scores with projections on coordinate planes

Usage

plot3DWithProj(
  pc,
  dims = c(1, 2, 3),
  plotProj = TRUE,
  grid = TRUE,
  col = 1,
  ff = 0.5,
  theta = -45,
  phi = 25
)

Arguments

pc	An rppca object
dims	integer vector, which PCs to plot, defauts to 1:3
plotProj	logical, whether to plot the projections
grid	logical, wheter to plot grids
col	the dot colours, integer or string, scalar or vector
ff	numeric, offset for projection (proportion of the orthogonal axis's range)
theta, phi	polar coordinates in degrees. theta rotates round the vertical axis. phi rotates round the horizontal axis.

Value

nothing

Examples

ped <- pedigree(pedMeta$fid,
pedMeta$mid,
pedMeta$id
)
pc <- rppca(ped)
plot3DWithProj(pc, col=as.numeric(factor(pedMeta$population)))
