Dear learned experts of R,
I was writing a book through RStudio-Rmarkdown and had finally compiled it
successfully based on R package R-3.6.2. Afterwards, I updated my R-3.6.2
to R-4.0.0 and even later to R-4.0.1.
Then, the publishers demanded to recompile the book with font embedding, so
I tried to recompile the book, when I found the following error:
"Error in (dm - 1) %*% ff : non-conformable arguments"
For convenience and reproducibility of the error, I am giving below the
same code chunk as an R-Script-Example, wherein the error is occurring in
the plot() function with the input of an aov() object.
R-Script-Example producing error:
==========================
setwd("E:/AKS-DATA-New/Software/R and allied
packages/R-Markdown/knitr/MyBooks/STAT-512_STAT-564")
getwd()
#After Upgrading to R-4.0.0 and even in R-4.0.1 following error in "plot()"
function occurs:
Block=c(1,1,1,1,2,2,2,2,3,3,3,3)
Permanganate=c("without","without","with","with","without","without","with","with","without","without","with","with")
Sample.Size=c(0.25,1,0.25,1,0.25,1,0.25,1,0.25,1,0.25,1)
Riboflavin=c(39.5,38.6,27.2,24.6,43.1,39.5,23.2,24.2,45.2,33,24.8,22.2)
#Creating data frame
sned.2x2.woint=data.frame(Block, Sample.Size, Permanganate, Riboflavin)
#Declaring Block, Sample.Size, Permanganate as factors
sned.2x2.woint$Block = factor(sned.2x2.woint$Block)
sned.2x2.woint$Sample.Size = factor(sned.2x2.woint$Sample.Size)
sned.2x2.woint$Permangate=factor(sned.2x2.woint$Permanganate)
#ANOVA of RBD when Block, Sample.Size, Permanganate are a fixed effects
sned.2x2.woint.aov1=aov(Riboflavin ~ Block + Sample.Size + Permanganate +
Sample.Size:Permanganate,data=sned.2x2.woint)
cat("ANOVA of RBD when Block, Sample.Size and Permanganate are fixed
effects:\n")
summary(sned.2x2.woint.aov1)

sned.2x2.woint.aov2=aov(Riboflavin ~ Block + Sample.Size + Permanganate,
data=sned.2x2.woint)
cat("ANOVA of RBD when Block, Sample.Size and Permanganate are fixed
effects:\n")
summary(sned.2x2.woint.aov2)
plot(sned.2x2.woint.aov2, which=1) #OK
plot(sned.2x2.woint.aov2, which=2) #Ok

plot(sned.2x2.woint.aov2, which=4) #OK
plot(sned.2x2.woint.aov2, which=5) #Error in (dm - 1) %*% ff :
non-conformable arguments
plot(sned.2x2.woint.aov2, which=6) #OK
=================================
I request the esteemed and learned experts of R to kindly me out to
overcome this error.
