stem.leaf(data, unit, m, Min, Max, rule.line = c("Dixon", "Velleman", "Sturges"),
style = c("Tukey", "bare"), trim.outliers = TRUE, depths = TRUE,
reverse.negative.leaves = TRUE, na.rm = FALSE, printresult = TRUE)
stem.leaf.backback(x,y, unit, m, Min, Max, rule.line = c("Dixon", "Velleman",
"Sturges"), style = c("Tukey", "bare"), trim.outliers = TRUE,
depths = TRUE, reverse.negative.leaves = TRUE, na.rm = FALSE,
printresult=TRUE, show.no.depths = FALSE, add.more.blanks = 0,
back.to.back = TRUE)
Arguments
data
a numeric vector of data
x
first dataset for stem.leaf.backback
y
first dataset for stem.leaf.backback
unit
leaf unit, as a power of 10 (e.g., 100, .01);
if unit is missing unit is choosen by stem.leaf.
m
number of parts (1, 2, or 5) into which each stem will be separated;
if m is missing the number of parts/stem
(m) is choosen by stem.leaf.
Min
smallest non-outlying value; omit for automatic choice.
Max
largest non-outlying value; omit for automatic choice.
rule.line
the rule to use for choosing the desired number of lines
in the display; "Dixon" = 10*log10(n); "Velleman" = 2*sqrt(n);
"Sturges" = 1 + log2(n); the default is "Dixon".
style
"Tukey" (the default) for "Tukey-style" divided stems;
"bare" for divided stems that simply repeat the stem digits.
trim.outliers
if TRUE (the default), outliers are placed on LO and
HI stems.
depths
if TRUE (the default), print a column of "depths" to the left of the
stems; the depth of the stem containing the median is the stem-count enclosed in
parentheses.
reverse.negative.leaves
if TRUE (the default), reverse direction the leaves on negative
stems (so, e.g., the leaf 9 comes before the leaf 8, etc.).
na.rm
if TRUE "NA" values are removed otherwise the number of NAs are counted.
printresult
if TRUE output of the stem and leaf display by cat.
show.no.depths
if TRUE no depths are printed.
add.more.blanks
number of blanks that are added besides the leaves.
back.to.back
if FALSE two parallel stem and leaf displays are constructed.
Details
Unlike the stem function in the base package, stem.leaf produces
classic stem-and-leaf displays, as described in Tukey's Exploratory Data Analysis.
The function stem.leaf.backback creates back-to-back stem and leaf displays.
Value
The computed stem and leaf display is printed out.
Invisibly stem.leaf returns the stem and leaf
display as a list containing the elements
info (legend), display (stem and leaf display as character vecter),
lower (very small values), upper (very large values), depths (vector of depths),
stem (stem information as a vector), and leaves (vector of leaves).
