Plot Results from a GSLCCA Analysis
Description
Plot ‘signatures’ (loadings of the Y matrix) or (projected) observed and fitted values (Y and X scores) from an “gslcca” object.
Usage
1 2 3 4 5 6 7  ## S3 method for class 'gslcca'
plot(x, type = "signature", series = x$treatment,
mean = FALSE, overlay = length(agrep(type, "signature")),
ask = dev.interactive(), lattice = !length(agrep(type, "signature")),
main = NULL, xlab = NULL, ylab = NULL, col = NULL, lty = 1, lwd = 1.5,
pch = NULL, legend.x = "topright", space = "bottom", corner = NULL,
columns = 2, ...)

Arguments
x 
an object of class 
type 
the type of plot: either 
series 
if 
mean 
logical: if 
overlay 
for 
ask 
logical: if 
lattice 
logical: if 
main 
an overall title for the plot. 
xlab 
a title for the x axis. 
ylab 
a title for the y axis. 
col 
a vector specifying a colour palette to use for the
lines/points. By default the palette is specified by

lty 
a vector of line types, see 
lwd 
a vector of line widths, see 
pch 
a vector of plotting characters, see 
legend.x 
a character vector to use in the legend.

Details
For type = "signature"
, the loadings of the Y
matrix from the GSLCCA analysis are displayed for each subject or
their average is displayed, as specified by individual
. When both
individual
and overlay
are TRUE
, the arguments
col
, lty
and legend.x
control the line style and
legend text for each subject.
For type = "fitted"
, the X scores are
displayed with lines. If there are multiple X scores
for each time point, then a line is displayed for each times series
specified by series
(usually the treatment factor used in
GSLCCA) and the arguments col
, lty
,
pch
and legend.x
control the display for each
series. By default, grey or black is used to display values
corresponding to the reference treatment (specified by x$ref
).
For type = "scores"
the X scores are displayed as
for type = "fitted"
and points are added for the Y
scores, again coloured by series
.
