| as.data.frame.psData {fitPS} | R Documentation |
Converts an object of class psData to a data.frame
Description
Converts an object of class psData—see readData—to a
data.frame that can be used with in functions in other packages such as
vglm to fit more complicated models.
Usage
## S3 method for class 'psData'
as.data.frame(x, ...)
Arguments
x |
an object of class |
... |
any other arguments passed to |
Details
If x is a psData object of type "P", i.e. it
relates to numbers of groups of glass, then a data.frame with a single variable
count will be return where count = rep(x$data$n + 1,
x$data$rn). The counts have one added to them because the zeta
distribution requires that the counts are greater than or equal to one. If
x is a psData object of type "P", i.e. it relates to
group sizes, then a data.frame with a single variable count
will be return where count = rep(x$data$n, x$data$rn).
Value
a data.frame with a single variable count. The number
of rows in the data.frame is equal to sum(x$data$rn).
Examples
p = readData(system.file("extdata", "p.xlsx", package = "fitPS"))
p.df = as.data.frame(p)
table(p.df$count)
p$data
