plot.PTAk  R Documentation 
Screeplot of singular values or superposed plot of modes for one or two components (1 dimensional scatterplot with spread labels or scatterplot on two dimensions).
## S3 method for class 'PTAk'
plot(x, labels = TRUE, mod = 1, nb1 = 1, nb2 = NULL,

nbvs = 40, RiskJack = NULL, method = "",ZoomInOut=NULL, Zlabels=NULL, Zcol=NULL,

x 
an object inheriting from class 
labels 
logical if 
mod 
vectors of the modes numbers to be plotted 
nb1 
number identifying the Principal Tensor to display on the vertical
axe, can be checked using 
nb2 
as nb1 to be displayed on the horizontal axe, if 
coefi 
coefficients to multiply components for all modes (not just the one in 
xylab 
logical to display axes labels 
ppch 
a vector of length at least 
lengthlabels 
a number or a vector of numbers of characters in labels to be used for display 
scree 
logical to display a screeplot of squared singular values as percent of total variation 
ordered 
logical used when displaying the screeplot with sorted
values (TRUE) or the order is given by output listing from

nbvs 
a maximum number of singular values to display on the screeplot or a vector of ranks 
max 
is the number of singular values to be considered as giving the perfect fit, NULL is the max possible in x 
rescaled 
boolean to rescale the y axis to 0100 
RiskJack

method 
default is 
ZoomInOut 
list used as [[1]] for xlim and [[2]] for ylim in xyplots instead of max and min range 
Zlabels 
used as labels instead of 
Zcol 
list of vectors of colours for Zlabels 
poslab 
integer or vector for 'pos' parameter, position of labels 
signedCTR 
logical to plot signedCTR instead of coordinates, see 
relCTR 
logical if

Plot components of one or two Principal Tensors, modes are superposed if more
than one is asked, or gives a screeplot. As it is using plot.default
at
some point some added features can be used in the ... part, especially
xlab=
may be useful when nb2=NULL
. Plots are superposed as they
correspond to the same Principal Tensor and so this gives insight to
interpretation of it, but careful is recommended as only overall
interpretation, once the Principal Tensor has been rebuilt mentally
(i.e. product of signs ...) to work out oppositions or associations. The
risk plot on top of a screeplot is an approximation of the Jacknife estimate of
the MSE in the choice of number of dimensions (see Besse et al.(1997)).
