Usage
prism.plots(formula, data, centerfunc = mean, spreadfunc = function(x) { return(sd(x)/sqrt(length(x))) }, def.axis = TRUE, jitter.y = FALSE, add = FALSE, start = 0, ...)
Arguments
formula
a formula object with the quantitative
variable as the response variable (e.g., Var~group).
data
a dataset containing the variables indicated
in formula
centerfunc
what function should be used to
indicate the center of the distribution. Defaults to
mean.
spreadfunc
what function should be used to
calculate the spread of the distribution. Defaults to sd.
Currently, it must be a symmetrical function. Future
implementations will have non-symmetric functions (e.g.,
interquartile range).
def.axis
Logical. Should the default axes be
used?
jitter.y
Logical. Should the y values be jittered
as well?
add
Should the plot be added to an existing plot?
start
What X value should the plot start at?
(defaults to zero)
