g.princals
It´s R-script to improve aesthetic plotting of princals function of
Gifi package
Proposal
g.princals is a function designed to address aesthetic issues
encountered when using plot.princals of “Gifi” package(1), which exclusively generates plots using a
“graphic” package. g.princals leverages the power of the ggplot2
package, renowned for producing high-quality visuals.this function just
produce, transplot, scree plot, loadplot and biplot for hierarchical
categoric variables(2).
Instruction
“g.princals” replaces the default “plot” function in R, generating
customized graphics for customer items. - x: call a object was generated
by princals(dataset). - plot.dim: Vector with dimensions to be plotted
with the default condition being set to c(1, 2). - var.subset: with the
default condition being set to”all” - max.plot.array: with the default
condition being set to 2. - stepvec: Vector whether step function should
be plotted (see details in princals/R Documentation).with the default
condition being set to NA. - col.lines: colour of line. Default
condition being set to “black”. - main: Title of picture. Default
condition being set to name of princals object. - show: Options to
choose are TRUE,FALSE,T,F,1 and 0. Default condition being set to “1”
mean it shows plots. - save: Options to choose are TRUE,FALSE,T,F,1 and
0. Default condition being set to “1” mean it saves plots. - name: label
or name of princals object. Default condition being set to name of
princals object. - units: unit of width/height in ‘mm’ - width: Default
condition being set to 250mm. - height: Default condition being set to
250mm. - res: resolution of pictures. Default condition being set to 300
pixels. - dispersion: dispersion of scores of object in loadplot.it is
decreased overdispersion or underdispersion. Default condition being set
to 3, it means, mean±3*standard deviation. - point.size.loadplot: it is
point size of loadplot. Default condition being set to 1. -
point.alpha.loadplot: it is point alpha(transparency) of loadplot.
Default condition being set to 0.1,
- language: choose a English or Spanish like language. Default condition
being set English. - legend.position: Options to choose are none, left,
right, bottom, and top. Default condition being set to right. it means
legend position is to right. - legend.group: Options to choose are
TRUE,FALSE,T,F,1 and 0. Default condition being set to “1” mean it shows
legend.
R code
Finally, it were showed a picture which generated by “g.princals”. If
the label names are lengthy, it’s advisable to shorten them into
acronyms.
