interaction2wt {HH} | R Documentation |
The main diagonal
displays boxplots for the main effects of each factor. The
off-diagonals show the interaction plots for each pair of factors.
The i,j
panel shows the same factors as the j,i
but with
the trace- and x-factor roles interchanged.
interaction2wt(x, ...) ## S3 method for class 'formula': interaction2wt(x, data = sys.parent(), responselab, ...) ## Default S3 method: interaction2wt(x, response.var, responselab = deparse(substitute(y)), relation = list(x = "free", y = "same"), x.relation = relation$x, y.relation = relation$y, digits = 3, x.between = c(1, rep(0, ncol(x) - 1)), y.between = NULL, cex = 0.75, panel.input = panel.interaction2wt, strip.input = strip.interaction2wt, par.strip.text.input = list(cex = 0.7), scales.additional, main.in = paste(responselab, ": main effects and 2-way interactions", sep = ""), xlab.in = TRUE, xlab = list(labels = ""), ylab = list(labels = ""), ..., main.cex)
Arguments when x
is a formula.
x |
The object on which method dispatch is carried out.
For the "formula" method, a formula describing the response
variable and factors.
The formula is generally of the form y ~ g1 + g2 + ... .
There may be one or more factors in the formula.
For the "default" method, data.frame of factors. This
is usually constructed by formula method from the input
data and the input formula.
|
data |
For the formula method, a data frame containing values for
any variables in the formula. In the R version,
if not found in data , or if
data is unspecified, the variables are looked for in the
environment of the formula.
|
responselab |
Character name of response variable, defaults to
the name of the response variable in the formula . |
... |
additional arguments, primarily trellis arguments. |
response.var |
For the "default" method, the
response variable. This is usually constructed by
formula method from the input data and the input formula. |
relation |
trellis argument. |
x.relation |
x value of relation argument. |
y.relation |
y value of relation argument. |
digits |
doesn't do anything at the moment |
x.between |
x value of relation argument. |
y.between |
y value of relation argument. |
cex |
S-Plus: changes the size of the median dot in the boxplots. R: doesn't do anything. |
panel.input |
panel function. Default is panel.interaction2wt . |
strip.input |
strip function. Default is strip.interaction2wt . |
par.strip.text.input |
par.strip.text argument. |
scales.additional |
additional arguments to scales argument. |
main.in |
Text of main title. |
xlab.in |
S-Plus: FALSE suppresses x labels in trellis. R: no effect. |
xlab |
No effect. |
ylab |
No effect. |
main.cex |
cex for main title. |
"trellis"
object containing the plot.
