sqparcoord -- Parallel-coordinates plot for sequence data

Syntax

sqparcoord [if] [in] [, options]

options               Description
-------------------------------------------------------------------------
ranks(numlist)        restrict tabulation on most frequent numlist
so                    apply same order similarity
offset(#)             add random noise to vertical position of sequence
lines
wlines(#)             highlight sequence lines according to frequency
gapinclude            include sequences with gaps in the tabulation
subsequence(a,b)      use only subsequence between positions a and b
twoway_options        options allowed for graph twoway

Description

sqparcoord draws sequences as a parallel-coordinates plot, with some

Options

ranks(numlist) is used to restrict the output to the most frequent
sequences. numlist refers to the position of the sequences in the
sorted frequency table. Hence, ranks(1) refers to the most frequent
sequence, whereas ranks(1/10) refers to the 10 most frequent
sequences. You can also specify ranks(2(2)20).

so is used to request a plot where only the order of elements is shown
(same-order similarity). With this option the sequences A-B-B-A and
A-B-A-A would both be drawn as if they were A-B-A. Option se, which
is available for many other SQ-Ados, is not applicable here.

offset(#) adds random noise to the vertical position of sequence lines.

wlines(#) is used draw more frequent sequences thicker than le,ss
frequent ones. Within the parentheses a number is used to specify the
factor by which the thickness is increased. The number given is
multiplied with the relative frequency of the sequences and passed as
relativesize to the option lwidth() of graph twoway line (also see
linewidthstyle).

gapinclude is used to include sequences with gaps. The default behavior
is to drop sequences with gaps from the graph. The gaps will be not
visible in the parallel-coordinates plot.  The term gap refers only
to missing values on the element variable within a sequence.
Sequences with missing values at the beginning and at the end of a
sequence are included in any case. You might consider using sqset
with option trim to get rid of superfluous missings (see sq for
details.)

subsequence(a,b) is used to include only the part of the sequence that is
between position a and b, whereby a and b refer to the position
defined in the order variable.

twoway_options are a set of common options supported by all twoway
commands; see twoway_options.
