as.data.frame.pairwiseMEP: Coerce pairwiseMEP objects to data.frames

Description

Coerces the output of the function pairwiseMEP to a data.frame.

Usage

## S3 method for class 'pairwiseMEP':
as.data.frame(x, row.names = NULL,
 optional = FALSE, whichep = NULL, ...)

Arguments

x

an object of class pairwiseMEP as can be obtained by calling pairwiseMEP

row.names

as in as.data.frame

optional

as in as.data.frame

whichep

a vector of integers or character strings, indexing which endpoints (which response variables) from object x shall be coerced to a data.frame; if omitted (default), all endpoints are coerced to a data.frame

...

Further arguments to be passed to as.data.frame

Value

• A data.frame with columns
• estimate
  numeric, the point estimates
• lower
  numeric, the lower confidence limits
• upper
  numeric, the upper confidence limits
• comparison
  character, the name of the groupwise comparison
• by
  optional, character, the name of subset of the original data.frame
• response
  character, the name of the response variable
• method
  character, the name of the method used for calculation of the lower and upper limits, see pairwiseMEP

Examples

x1<-rnorm(120,20,2)
x2<-rnorm(120,100,8)
x3<-rpois(120,10)
x4<-rnbinom(120,mu=10, size=10)
A<-rep(c("a1","a2","a3"), c(40,40,40))
B<-rep(rep(c("b1","b2","b3","b4"), c(10,10,10,10)), times=3)

dat<-data.frame(x1=x1, x2=x2, x3=x3, x4=x4, A=A, B=B)

test<-pairwiseMEP(x=dat,
 ep=c("x1","x2","x3", "x4"),
 f="A", by="B",
 method=c("Param.ratio","Param.ratio","Negbin.ratio","Negbin.ratio"))

test
