Constructs a various tours of data space
randomPath(data, length = 10, reorder = TRUE, conditionvars = NULL, ...)
seqPath(data, length = 10, reorder = FALSE, conditionvars = NULL, ...)
alongPath(data, var, length = 10, current = NULL, ...)A dataframe
Path length, defaults to 10
If TRUE (default) uses DendSer to reorder the path dser
A vector of variable names. The returned tour is for this subset of variables.
ignored
A variable name for alongPath
Default value of variables for alongPath
A dataframe with the path
randomPath(): Constructs a tour of data space following random observations
seqPath(): Constructs a tour of data space following first length observations
alongPath(): Constructs a tour of data space of length equi-spaced values in the range of var.
If var is a factor, its levels are used.
