# S3 method for formula
bootCor(formula, data, subset, ...)
Value
The command invisibly returns the correlations of the resampled
observations.
Arguments
x
a numeric vector.
...
further arguments to be passed to or from methods.
y
a numeric vector.
conf.level
confidence level for the bootstrap ercentile interval.
B
number of times to resample (positive integer greater than 2).
plot.hist
a logical value. If TRUE, plot the bootstrap
distribution of the resampled correlation.
hist.title
a user supplied title for the histogram.
plot.qq
a logical value. If TRUE a normal quantile-quantile
plot of the bootstraped values is created.
legend.loc
location to place the legend. Options include
"topright", "topleft", "bottomright",
"bottomleft".
x.name
Label for variable x
y.name
Label for variable y
formula
a formula of the form lhs ~ rhs where lhs is a numeric variable giving the data values and rhs a factor with two levels giving the corresponding groups.
data
an optional data frame containing the variables in the formula formula.
By default the variables are taken from environment(formula).
subset
an optional vector specifying a subset of observations to be used.
Methods (by class)
default: Bootstrap the correlation of two numeric variables.
formula: Bootstrap the correlation of two numeric variables.
