ldata

ldata class definition and utilities

ldata is a list with two type of objects:

  • df is a data frame with the multivariate data with n rows.

  • ... fdata objects of class fdata with n rows.

Usage
ldata(df, ..., mfdata)

# S3 method for ldata names(x)

is.ldata(x)

# S3 method for ldata [(x, i, row = FALSE)

# S3 method for ldata subset(x, subset, ...)

# S3 method for ldata plot(x, ask = FALSE, color, var.name, ...)

Arguments
df

data frame

Further arguments passed to methods.

mfdata

list of fdata objects

i

index

row

logical If FALSE (by default), i index selects the variables. If TRUE, i index selects the observations.

subset

subset

ask

logilcal If TRUE (and the R session is interactive) the user is asked for input, before a new figure is drawn.

color

colors to interpolate; must be a valid argument to colorRampPalette.

var.name

name of continuous univariate variable used in color argument

ldata, x

object of class ldata
