矩阵在R中不一致地删除列名称 [英] Matrix dropping the column names inconsistently in R
本文介绍了矩阵在R中不一致地删除列名称的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个名为 foo
的小函数。当我使用 m0
运行它时,它会正确显示列名。但是当我将它与 m1
一起使用时, foo
会忽略所有列名。
I have a small function called foo
. When I run it with m0
, it correctly shows the column names. But when I use it with m1
, foo
omits all column names.
Is there a fix for that?
library(lme4)
library(Matrix)
sng <- read.csv('https://raw.githubusercontent.com/rnorouzian/e/master/sng.csv')
m0 <- lmer(y ~ A * B * C + (A * B * C | group), data = sng)
m1 <- lmer(y ~ A * B * C + (A * B * C || group), data = sng)
foo <- function(fit){
vc <- VarCorr(fit)
as.matrix(Matrix::bdiag(vc))
}
# EXAMPLES OF USE:
foo(m0) # SHOWS COLUMNAMES FINE :-)
foo(m1) # OMITS COLUMNNAMES ALL :-(
推荐答案
尝试这种方法,它看起来像是输出矩阵和 VarCorr()中列表长度的问题
。这里的代码:
Try this approach. It looks like an issue with the output matrix and the length of the list in VarCorr()
. Here the code:
library(lme4)
library(Matrix)
#Data and models
sng <- read.csv('https://raw.githubusercontent.com/rnorouzian/e/master/sng.csv')
m0 <- lmer(y ~ A * B * C + (A * B * C | group), data = sng)
m1 <- lmer(y ~ A * B * C + (A * B * C || group), data = sng)
#Function
foo <- function(fit){
vc <- VarCorr(fit)
if(length(vc)==1)
{
y <- as.matrix(Matrix::bdiag(vc))
} else
{
z <- do.call(rbind,vc)
y <- as.matrix(Matrix::bdiag(vc))
dimnames(y)[[1]] <- rownames(z)
dimnames(y)[[2]] <- rownames(z)
}
return(y)
}
#Apply
foo(m0)
foo(m1)
输出:
foo(m0)
