在candisc::cancor输出上使用xtable函数
我想在在candisc::cancor输出上使用xtable函数,r,knitr,sweave,xtable,rnw,R,Knitr,Sweave,Xtable,Rnw,我想在candisc::cancor输出上使用xtable函数。但是我想不出来 library(xtable) library(candisc) data(Rohwer, package="heplots") X <- as.matrix(Rohwer[,6:10]) # the PA tests Y <- as.matrix(Rohwer[,3:5]) # the aptitude/ability variables (cc <- cancor(X, Y, set.na
candisc::cancor
输出上使用xtable
函数。但是我想不出来
library(xtable)
library(candisc)
data(Rohwer, package="heplots")
X <- as.matrix(Rohwer[,6:10]) # the PA tests
Y <- as.matrix(Rohwer[,3:5]) # the aptitude/ability variables
(cc <- cancor(X, Y, set.names=c("PA", "Ability")))
Canonical correlation analysis of:
5 PA variables: n, s, ns, na, ss

xtable(cc)
Error in UseMethod("xtable") :
no applicable method for 'xtable' applied to an object of class "cancor"
库(xtable)
图书馆(candisc)
数据(Roower,package=“heplots”)
X如果你看methods(xtable)
没有用于cancor
对象的方法,但是有xtable.data.frame
我们希望可以使用,因为cancor
的输出看起来像data.frames
但是,cancor
不会返回这些值-请查看str(cc)
。它们是通过print
方法计算的。查看candisc:::print.cancor
因此,创建一个快速提取函数来生成cancor
输出为data.frames
outfun <- function(X) {
CanR = X$cancor
CanRSQ = CanR^2
Eigen = CanRSQ/(1 - CanRSQ)
percent = 100 * Eigen/sum(Eigen)
cum = cumsum(percent)
list(tab1 = data.frame(CanR, CanRSQ, Eigen, percent, cum) ,
tab2 = as.data.frame(candisc:::Wilks.cancor(X)))
}
您可以调整helper函数来提取标题,然后将标题作为参数传递给xtable.data.frame
一个快速的答案可能会让你开始非常感谢你的帮助和提供非常有用的答案。非常感谢。感谢您在as.data.frame(candisc:::Wilks.cancor(cc))
中做了一些更改,因为cc
未定义。干杯,再次忘记在发布之前清除我的工作区;)
(out <- outfun(cc))
# or run it like
out <- outfun(cancor(X, Y, set.names=c("PA", "Ability")))
