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.
ldata(df, ..., mfdata) ## S3 method for class 'ldata' names(x) is.ldata(x) ## S3 method for class 'ldata' x[i, row = FALSE] ## S3 method for class 'ldata' subset(x, subset, ...) ## S3 method for class 'ldata' plot(x, ask = FALSE, color, var.name, ...)
df |

Further arguments passed to methods. |
mfdata |

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 |
var.name |
name of continuous univariate variable used in |
ldata, x |
