Plots a population of models (or a single model) objects as barplots of scaled coefficients.

Plots an model or a population of models as a barplots, representing each feature, the length being the coefficient

Usage

plotPopulation(
  pop,
  X,
  y,
  sort.features = FALSE,
  sort.ind = NULL,
  col.sign = c("deepskyblue1", "firebrick1"),
  ncol = 10,
  slim = FALSE,
  importance = FALSE
)

Arguments

pop:

a population of models to plot

X:

the data matrix with variables in the rows and observations in the columns

y:

the class vector

sort.features:

wether the features need to be sorted by correlation with 'y' or not

sort.ind:

computing sorting can take time if computed for every model and can be computed outside the function and passed as a parameter

col.sign:

the colors of the cofficients based on the sign of the coefficients (default: -1=deepskyblue1,1:firebrick1)

ncol:

number of graphics for each line (default: 10)

slim:

plot without axis information (default:FALSE)

importance:

the importance (mda) of the features in crossval
